Chapter 1: Introduction

Introduction to the Router

Thank you for choosing the Linksys 10/100 4-Port VPN Router. The Router lets multiple computers in your office share an Internet connection. The dual Internet ports let you connect a second Internet line as a backup, or you can use both Internet ports at the same time, allowing the Router to manage bandwidth demands for maximum efficiency.
The Router features a built-in, 4-port, full-duplex, 10/100 Ethernet switch to connect four computers directly, or you can connect more switches to expand your network. For remote connections, up to 50 remote office or traveling users can securely connect to your office network using the Router’s Virtual Private Network (VPN) capability.
Use the browser-based utility to configure settings and run convenient wizards that will help you set up the Router and its access rules.
For an IPSec VPN tunnel, the VPN Router and any computer with the built-in IPSec Security Manager (Windows 2000 and XP) can create a VPN tunnel using IPSec (Windows Vista uses a similar utility). Other Windows operating systems require additional, third-party VPN client software applications that support IPSec to be installed.
NOTE: The 10/100 4-Port VPN Router supports
IPSec VPN client software, including the Linksys QuickVPN software. (For more information, refer to “Appendix B: Linksys QuickVPN for Windows 2000, XP, or Vista”.)
For a PPTP VPN tunnel, the 10/100 4-Port VPN Router and any computer running Windows 2000 or XP can create a VPN tunnel using PPTP.

VPN Examples

The following are examples of a VPN tunnel between two VPN routers and a VPN tunnel between a computer using VPN client software and a VPN router.

VPN Router to VPN Router

Introduction to VPNs

A VPN is a connection between two endpoints—a VPN Router, for instance—in different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This establishes a private network that can send data securely between these two locations or networks.
The private network is established by creating a “tunnel”. A VPN tunnel connects the two computers or networks and allows data to be transmitted over the Internet as if it were still within those networks. A VPN tunnel uses industry-standard encryption and authentication techniques to secure the data sent between the two networks.
Virtual Private Networking was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. It can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road.
There are two basic ways to create a VPN connection:
VPN Router to VPN Router
For example, at home, a telecommuter uses his VPN Router for his always-on Internet connection. His Router is configured with his office’s VPN settings. When he connects to his office’s router, the two routers create a VPN tunnel, encrypting and decrypting data. As VPNs use the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the central office’s network, as if he were physically connected.

The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with VPN client software can be one of the two endpoints.

Computer (using VPN client software) to VPN Router

The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman connects to her Internet Service Provider (ISP). Her notebook computer has VPN client software that is configured with her office’s VPN settings. She accesses the VPN client software and connects to the VPN Router at the central office. As VPNs use the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure connection to the central office’s network, as if she were physically connected.

Forwarding

Port Range Forwarding
Port forwarding can be used to set up public services on your network. When users from the Internet make certain requests on your network, the Router can forward those requests to computers equipped to handle the requests. If, for example, you set the port number 80 (HTTP) to be forwarded to IP address 192.168.1.2, then all HTTP requests from outside users will be forwarded to 192.168.1.2.
NOTE: You must disable the Router’s DHCP
function to use port forwarding.
You may use this function to establish a web server or FTP server via an IP gateway. Make sure that you enter a valid IP address. (You may need to establish a static IP address in order to properly run an Internet server.) For added security, Internet users will be able to communicate with the server, but they will not actually be connected. The packets will simply be forwarded through the Router.

Setup > One-to-One NAT
One-to-One NAT (Network Address Translation) creates a relationship that maps valid external IP addresses to internal IP addresses hidden by NAT. A device with an internal IP address may be accessed at the corresponding external valid IP address.
To create this relationship, define internal and external IP address ranges of equal length. Once the relationship is defined, the device with the first internal IP address is accessible at the first IP address in the external IP address range, and so forth.
For example, you have a Local Area Network (LAN) for which the ISP has assigned the IP address range of 209.19.28.16 to 209.19.28.31, with 209.19.28.16 used as the Wide Area Network (WAN) or NAT public IP address of the Router. The address range of 192.168.168.1 to 192.168.168.255 is used for the devices on the LAN. With One-to-One NAT, the devices with the internal IP addresses of 192.168.168.2 to 192.168.168.15 may be accessed at the corresponding external IP addresses.
NOTE: The Router’s WAN IP address should not
be included in the range you specify.

Advanced Routing

Dynamic Routing
The Router’s dynamic routing feature can be used, so the Router will automatically adjust to physical changes in the network’s layout. Using the dynamic RIP protocol, the Router calculates the most efficient route for the network’s data packets to travel between the source and the destination, based upon the shortest paths. The RIP protocol regularly broadcasts routing information to other routers on the network. It determines the route that the network packets take based on the fewest number of hops between the source and the destination.
Working Mode Select Gateway mode if the Router
is hosting your network’s connection to the Internet. Select Router mode if the Router exists on a network with other routers, including a separate network gateway that handles the Internet connection. In Router mode, any computer connected to the Router will not be able to connect to the Internet unless you have another router function as the gateway.
RIP (Routing Information Protocol) To use dynamic
routing for communication of network data, select
Enabled. Otherwise, keep the default, Disabled.
Receive RIP versions To use dynamic routing for
reception of network data, select the protocol you want:

Static Routing
If the Router is connected to more than one network or there are multiple routers installed on your network, it may be necessary to set up static routes. The static routing function determines the path that data follows over your network before and after it passes through the Router. You can use static routing to allow different IP domain users to access the Internet through the Router.
Static routing is a powerful feature that should be used by advanced users only. In many cases, it is better to use dynamic routing because it enables the Router to automatically adjust to physical changes in the network’s layout.

To create a static route entry, enter the following information:
Destination IP Enter the network address of the remote
LAN segment. For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP, while the last field should be 0.
Subnet Mask Enter the subnet mask used on the
destination LAN IP domain. For Class C IP domains, the subnet mask is 255.255.255.0.
Default Gateway Enter the IP address of the router of the
network, for which this static route is created. For example, if this network is connected to the local router’s LAN port through another router, use the WAN IP address of that router.
Hop Count Enter the appropriate value (maximum is 15).
This indicates the number of nodes that a data packet passes through before reaching its destination. A node is any device on the network, such as a computer or router.
Interface Select the appropriate interface. The Interface
tells you whether your network is on the LAN, WAN1, or WAN2/DMZ. If the gateway router is on a LAN port, then select LAN. If you’re connecting to another network through the Internet, select the appropriate WAN port option.

DHCP > Setup

The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server automatically assigns available IP addresses to computers on your network. If you choose to enable the DHCP server option, all of the computers on your LAN must be set to obtain an IP address automatically from a DHCP server. (By default, Windows computers are set to obtain an IP automatically.)
If the Router’s DHCP server function is disabled, do one of the following:
Configure the IP address, subnet mask, and DNS settings of every computer on your network. (Make sure you do not assign the same IP address to different computers.)

General

Firewall The firewall is enabled by default. If you disable
it, then the SPI, DoS, and Block WAN Request features, Access Rules, and Content Filters will also be disabled, and the Remote Management feature will be enabled.
SPI (Stateful Packet Inspection) This option is enabled
by default. The Router’s firewall uses Stateful Packet Inspection to review the information that passes through the firewall. It inspects all packets based on the established connection, prior to passing the packets for processing through a higher protocol layer.
DoS (Denial of Service) This option is enabled by default.
It protects internal networks from Internet attacks, such
10/100 4-Port VPN Router
29
Chapter 4
Advanced Configuration
as SYN Flooding, Smurf, LAND, Ping of Death, IP Spoofing, and reassembly attacks.
Block WAN Request This option is enabled by default.
Using this feature, the Router drops both unaccepted TCP request and ICMP packets from the WAN side. Hackers will not find the Router by pinging the WAN IP address.
Remote Management This option is disabled by
default. If you want to manage the Router through a WAN connection, first change the password on the Setup > Password screen (this prevents any user from accessing the Router with the default password). Then select Enable for the Remote Management setting, and enter the port number (port 80, the default, or 8080 is usually used).
NOTE: If the Remote Management feature on
the Firewall > General screen has been enabled, then users with administrative privileges can remotely access the web-based utility. Use http://<WAN IP address of the Router>, or use https://<WAN IP address of the Router> if you have enabled the HTTPS feature.
HTTPS HTTPS is a secured HTTP session. If Remote
Management is enabled, HTTPS is enabled by default.
ActiveX ActiveX is a programming language for
websites. If you deny ActiveX, you run the risk of losing access to Internet sites created using this programming language. To block ActiveX, select ActiveX.
Access to HTTP Proxy Servers Use of WAN proxy
servers may compromise the Router’s security. If you block access to HTTP proxy servers, then you block access to WAN proxy servers. To block access, select
Access to HTTP Proxy Servers.
Don’t block Java/ActiveX/Cookies/Proxy to Trusted Domains To keep trusted sites unblocked, select
this option. You will be able to specify a list of trusted domains.
Click Save Settings to save your changes, or click Cancel Changes to undo them.

Firewall > Access Rules

Access rules evaluate network traffic to decide whether or not it is allowed to pass through the Router’s firewall. Access Rules look specifically at a data transmission’s source IP address, destination IP address, and IP protocol type, and you can apply each access rule according to a different schedule.
NOTE: If you disable the HTTPS feature, then
you also disable the Linksys QuickVPN service on the Router.
Multicast Pass Through This option is disabled by default.
IP multicasting occurs when a single data transmission is sent to multiple recipients at the same time. Using this feature, the Router allows IP multicast packets to be forwarded to the appropriate LAN devices. Multicast Pass Through is used for Internet games, videoconferencing, and multimedia applications.
MTU (Maximum Transmission Unit) This setting
specifies the largest packet size permitted for network transmission. In most cases, keep the default, Auto. To specify the MTU, select Manual, and then enter the maximum MTU size.
Restrict WEB Features
Block Select the filters you want to use.
Java Java is a programming language for websites. If
you deny Java applets, you run the risk of losing access to Internet sites created using this programming language. To block Java applets, select Java.
Cookies A cookie is data stored on your PC and used
by Internet sites when you interact with them. To block cookies, select Cookies.
With the use of custom rules, it is possible to disable all firewall protection or block all access to the Internet, so use extreme caution when creating or deleting access rules.
The Router has the following default rules:
All traffic from the LAN to the WAN is allowed.
All traffic from the WAN to the LAN is denied.
All traffic from the LAN to the DMZ is allowed.
All traffic from the DMZ to the LAN is denied.
All traffic from the WAN to the DMZ is allowed.
All traffic from the DMZ to the WAN is allowed.
Custom rules can be created to override the above default rules, but there are four additional default rules that will be always active and cannot be overridden by any custom rules.
HTTP service from the LAN to the Router is always allowed.
DHCP service from the LAN is always allowed.
DNS service from the LAN is always allowed.
Ping service from the LAN to the Router is always allowed.

In order for any encryption to occur, the two ends of a VPN tunnel must agree on the methods of encryption, decryption, and authentication. This is done by sharing a key to the encryption code. For key management, the default mode is IKE with Preshared Key.
Keying Mode Select IKE with Preshared Key or Manual.
Both ends of a VPN tunnel must use the same mode of key management. After you have selected the mode, the settings available on this screen may change, depending on the selection you have made. Follow the instructions for the mode you want to use.
NOTE: The Remote Security Group Type you
select should match the Local Security Group Type selected on the VPN device at the other end of the tunnel.
After you have selected the Remote Security Group Type, the settings available on this screen may change, depending on which selection you have made.
IP
Only the computer with a specific IP address will be able to access the tunnel.
Remote Security Group Type > IP
IP address Enter the appropriate IP address.
Subnet
The default is Subnet. All computers on the remote subnet will be able to access the tunnel.

IKE with Preshared Key
IKE is an Internet Key Exchange protocol used to negotiate key material for Security Association (SA). IKE uses the Preshared Key to authenticate the remote IKE peer.
Phase 1 DH Group Phase 1 is used to create the SA. DH
(Diffie-Hellman) is a key exchange protocol used during Phase 1 of the authentication process to establish pre­shared keys. There are three groups of different prime key lengths. Group 1 is 768 bits, and Group 2 is 1,024 bits. Group 5 is 1,536 bits. If network speed is preferred, select
Group 1. If network security is preferred, select Group 5.
Phase 1 Encryption Select a method of encryption: DES
(56-bit), 3DES (168-bit), AES-128 (128-bit), AES-192 (192­bit), or AES-256 (256-bit). The method determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is the most secure. Make sure both ends of the VPN tunnel use the same encryption method.
Phase 1 Authentication Select a method of
authentication, MD5 or SHA. The authentication method determines how the ESP packets are validated. MD5 is

Advanced Configuration
a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same authentication method.
Phase 1 SA Life Time Configure the length of time a VPN
tunnel is active in Phase 1. The default value is 28800 seconds.
Perfect Forward Secrecy If the Perfect Forward Secrecy
(PFS) feature is enabled, IKE Phase 2 negotiation will generate new key material for IP traffic encryption and authentication, so hackers using brute force to break encryption keys will not be able to obtain future IPSec keys.
Phase 2 DH Group If the Perfect Forward Secrecy feature
is disabled, then no new keys will be generated, so you do not need to set the Phase 2 DH Group (the key for Phase 2 will match the key in Phase 1).
There are three groups of different prime key lengths. Group 1 is 768 bits, and Group 2 is 1,024 bits. Group 5 is 1,536 bits. If network speed is preferred, select Group 1. If network security is preferred, select Group 5. You do not have to use the same DH Group that you used for Phase 1.
Phase 2 Encryption Phase 2 is used to create one or
more IPSec SAs, which are then used to key IPSec sessions. Select a method of encryption: NULL, DES (56-bit), 3DES (168-bit), AES-128 (128-bit), AES-192 (192-bit), or AES- 256 (256-bit). It determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is the most secure. Both ends of the VPN tunnel must use the same Phase 2 Encryption setting.
Phase 2 Authentication Select a method of
authentication, NULL, MD5, or SHA. The authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA is recommended because it is more secure. Both ends of the VPN tunnel must use the same Phase 2 Authentication setting.
Phase 2 SA Life Time Configure the length of time a VPN
tunnel is active in Phase 2. The default is 3600 seconds.
Preshared Key This specifies the pre-shared key used
to authenticate the remote IKE peer. Enter a key of keyboard and hexadecimal characters, e.g., My_@123 or 4d795f40313233. This field allows a maximum of 30 characters and/or hexadecimal values. Both ends of the VPN tunnel must use the same Preshared Key. It is strongly recommended that you change the Preshared Key periodically to maximize VPN security.
Manual
If you select Manual, you generate the key yourself, and no key negotiation is needed. Manual key management is used in small static environments or for troubleshooting purposes.
Keying Mode > Manual
Incoming and Outgoing SPI (Security Parameter Index) SPI is carried in the ESP (Encapsulating Security
Payload Protocol) header and enables the receiver and sender to select the SA, under which a packet should be processed. Hexadecimal values is acceptable, and the valid range is 100~ffffffff. Each tunnel must have a unique Incoming SPI and Outgoing SPI. No two tunnels share the same SPI. The Incoming SPI here must match the Outgoing SPI value at the other end of the tunnel, and vice versa.
Encryption Select a method of encryption, DES or 3DES.
This determines the length of the key used to encrypt or decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit encryption. 3DES is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same encryption method.
Authentication Select a method of authentication, MD5
or SHA1. The Authentication method determines how the ESP packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA1 is recommended because it is more secure. Make sure both ends of the VPN tunnel use the same authentication method.
Encryption Key This field specifies a key used to encrypt
and decrypt IP traffic. Enter a key of hexadecimal values. If DES is selected, the Encryption Key is 16-bit, which requires 16 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Encryption Key will be automatically completed with zeroes, so the Encryption Key will be 16-bit. If 3DES is selected, the Encryption Key is 48-bit, which requires 40 hexadecimal values. If you do not enter enough hexadecimal values, then the rest of the Encryption Key will be automatically completed with zeroes, so the Encryption Key will be 48­bit. Make sure both ends of the VPN tunnel use the same Encryption Key.
Authentication Key This field specifies a key used to
authenticate IP traffic. Enter a key of hexadecimal values.

If you select one of the Dynamic IP types for the Remote Security Gateway Type setting, then Main Mode will be unavailable, so Aggressive Mode will be used.
Compress (Support IP Payload Compression Protocol (IP Comp)) IP Payload Compression is a protocol that
reduces the size of IP datagrams. Select this option if you want the Router to propose compression when it initiates a connection. If the responders reject this proposal, then the Router will not implement compression. When the Router works as a responder, it will always accept compression, even if compression is not enabled.

Introduction

The 10/100 4-Port VPN Router (model number: RV042) supports IPSec VPN client software, including the Linksys QuickVPN software (also known as the Linksys VPN client).
The Router supports up to 50 Linksys QuickVPN clients free of charge. If the Router you have only supports up to ten clients, then upgrade its firmware. Refer to “Appendix F: Firmware Upgrade” for instructions.

Computer (using VPN client software) to VPN Router

You can create a VPN tunnel between a computer using VPN client software and a VPN router. The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman connects to her Internet Service Provider (ISP). Her notebook computer has VPN client software that is configured with her office’s VPN settings. She accesses the VPN client software and connects to the VPN Router at the central office. As VPNs use the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure connection to the central office’s network, as if she were physically connected.

Appendix D
IPSec NAT Traversal

Appendix D: IPSec NAT Traversal

Overview

Network Address Translation (NAT) traversal is a technique developed so that data protected by IPSec can pass through a NAT. (See NAT 1 and NAT 2 in the diagram.) Since IPSec provides integrity for the entire IP datagram, any changes to the IP addressing will invalidate the data. To resolve this issue, NAT traversal appends a new IP and UDP header to the incoming datagram, ensuring that no changes are made to the incoming datagram stream.
This chapter discusses two scenarios. In the first scenario, Router A initiates IKE negotiation, while in the second scenario, Router B initiates IKE negotiation. In the second scenario, since the IKE responder is behind a NAT device, a one-to-one NAT rule is required on the NAT device.

Before You Begin

The following is a list of equipment you need:
Two 4-Port SSL/IPSec VPN Routers (model number: RVL200), one of which is connected to the Internet

IPSec NAT Traversal

Configuration of Scenario 2

In this scenario, Router B is the RVL200 Initiator, while Router A is the RVL200 Responder. Router B will have the Remote Security Gateway IP address set to a public IP address that is associated with the WAN IP address of Router A, which is behind the NAT. Hence the public IP address (192.168.99.1) must be mapped to the WAN IP address (192.168.11.101, a private IP address) of Router A through the two one-to-one NAT rules:
192.168.99.1 => 192.168.111.11 (on NAT 2)
192.168.111.11 => 192.168.11.101 (on NAT 1)
WAN: 192.168.99.11 NAT 2 - RV042 LAN: 192.168.111.1
WAN: 192.168.99.22 Router B - RVL200 Initiator LAN: 192.168.2.0/24

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.

Appendix J
Software License Agreement
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software—to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation’s software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author’s protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors’ reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone’s free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The “Program”, below, refers to any such program or work, and a “work based on the Program” means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term “modification”.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.
You may copy and distribute verbatim copies of the 1. Program’s source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
You may modify your copy or copies of the Program 2. or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
You must cause the modified files to carry a. prominent notices stating that you changed the files and the date of any change.
You must cause any work that you distribute or b. publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
If the modified program normally reads commands c. interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and

a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
You may copy and distribute the Program (or a 3. work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
Accompany it with the complete corresponding a. machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
Accompany it with a written offer, valid for at least b. three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
Accompany it with the information you received as c. to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program
in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
You may not copy, modify, sublicense, or distribute 4. the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
You are not required to accept this License, since you 5. have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
Each time you redistribute the Program (or any work 6. based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients’ exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
If, as a consequence of a court judgment or allegation 7. of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise)

Software License Agreement
that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
If the distribution and/or use of the Program is 8. restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
The Free Software Foundation may publish revised 9. and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
may choose any version ever published by the Free Software Foundation.
If you wish to incorporate parts of the Program into 10. other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 11. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR 12. AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS

END OF SCHEDULE 2

Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and “any later version”, you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you
