Features

The BiPAC 7402R2 ADSL2+ VPN Firewall Router combines high-speed Internet access, networking, and advanced security for office local area network. It provides:

security features including multiple VPN tunnels with

Express Internet Access

The router complies with ADSL worldwide standards. It supports downstream rate up to 12/24

Mbps with ADSL2/2+, 8Mbps with ADSL. Users enjoy not only high-speed ADSL services but also

broadband multimedia applications such as interactive gaming, video streaming and real-time audio much easier and faster than ever. It is compliant with Multi-Mode standard (ANSI T1.413,

Issue 2; G.dmt (ITU G.992.1); G.lite (ITU G.992.2); G.hs (ITU G994.1); G.dmt.bis (ITU G.992.3); G.dmt.bisplus (ITU G.992.5)).

Fast Ethernet Switch

A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI and MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or crossover cable can be used directly for auto detection.

Multi-Protocol to Establish A Connection

Supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516) and IPoA (RFC1577) to establish a connection with the ISP. The product also supports VC-based and LLC-based multiplexing.

Quick Installation Wizard

Supports a WEB GUI page to install this device quickly. With this wizard, end users can enter the information easily which they get from their ISP, then surf the Internet immediately.

Universal Plug and Play (UPnP) and UPnP NAT Traversal

This protocol is used to enable simple and robust connectivity among stand-alone devices and PCs from many different vendors. It makes network simple and affordable for users. UPnP architecture leverages TCP/IP and the Web to enable seamless proximity networking in addition to control and data transfer among networked devices. With this feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly.

Chapter 1: Introduction

BiPAC 7402R2 ADSL2+ VPN Firewall Router

Network Address Translation (NAT)

Allows multi-users to access outside resources such as the Internet simultaneously with one IP address/one Internet access account. Many application layer gateway (ALG) are supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others.

Firewall

Supports SOHO firewall with NAT technology. Automatically detects and blocks Denial of Service (DoS) attacks. The URL blocking, packet filtering and SPI (Stateful Packet Inspection) are also supported. The hacker’s attack will be recorded associated with timestamp in the security logging area. More firewall functions will always be implemented through updated firmware releases.

Domain Name System (DNS) relay

Provides an easy way to map the domain name (a friendly name for users such as

www.yahoo.com) and IP address. When local machine sets its DNS server with this router’s IP

address, every DNS conversion request packet from the PC to this router will be forwarded to the real DNS in the outside network.

Dynamic Domain Name System (DDNS)

The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname. This dynamic IP address is the WAN IP address. For example, to use the service, you must first apply for an account from a DDNS service like

http://www.dyndns.org/. More than 5 DDNS servers are

supported.

PPP over Ethernet (PPPoE)

Provides embedded PPPoE client function to establish a connection. Users can get greater

access speed without changing the operation concept, sharing the same ISP account and paying for one access account. No PPPoE client software is required for local computer. The Automatic Reconnect and Disconnect Timeout (Idle Timer) functions are provided, too.

Virtual Private Network (VPN)

Allows user to make a tunnel with a remote site directly to secure the data transmission among the connection. User can use embedded PPTP and L2TP client/server, IKE and IPSec which are supported by this router to make a VPN connection or users can run the PPTP client in PC and the router already provides IPSec and PPTP pass through function to establish a VPN connection if the user likes to run the PPTP client in his local computer.

Virtual Server (“port forwarding”)

Users can specify some services to be visible from outside users. The router can detect incoming service requests and forward either a single port or a range of ports to the specific local computer to handle it. For example, a user can assign a PC in the LAN acting as a WEB server inside and expose it to the outside network. Outside users can browse inside web servers directly while it is protected by NAT. A DMZ host setting is also provided to a local computer exposed to the outside network, Internet.

Rich Packet Filtering

Not only filters the packet based on IP address, but also based on Port numbers. It will filter packets from and to the Internet, and also provides a higher level of security control.

Dynamic Host Configuration Protocol (DHCP) client and server

In the WAN site, the DHCP client can get an IP address from the Internet Service Provider (ISP) automatically. In the LAN site, the DHCP server can allocate a range of client IP addresses and distribute them including IP address, subnet mask as well as DNS IP address to local computers. It provides an easy way to manage the local IP network.

Chapter 1: Introduction

BiPAC 7402R2 ADSL2+ VPN Firewall Router

Static and RIP1/2 Routing

Supports an easy static routing table or RIP1/2 routing protocol to support routing capability.

Simple Network Management Protocol (SNMP)

It is an easy way to remotely manage the router via SNMP.

Web based GUI

Supports web based GUI for configuration and management. It is user-friendly and comes with online help. It also supports remote management capability for remote users to configure and manage this product.

Firmware Upgradeable

Device can be upgraded to the latest firmware through the WEB based GUI.

Rich management interfaces

Supports flexible management interfaces with local console port, LAN port, and WAN port. Users can use terminal applications through the console port to configure and manage the device, or Telnet, WEB GUI, and SNMP through LAN or WAN ports to configure and manage the device.

Cabling

The most common problem associated with Ethernet is bad cabling or ADSL line(s). Make sure that all connected devices are turned on. On the front of the product is a bank of LEDs. Verify that the LAN Link and ADSL line LEDs are lit. If they are not, verify that you are using the proper cables.

Ensure that all other devices connected to the same telephone line as your router (e.g. telephones, fax machines, analogue modems) have a line filter connected between them and the wall socket (unless you are using a Central Splitter or Central Filter installed by a qualified and licensed electrician), and ensure that all line filters are correctly installed and the right way around.

Missing line filters or line filters installed the wrong way around can cause problems with your ADSL connection, including causing frequent disconnections.

Chapter 2: Installing the Router

BiPAC 7402R2 ADSL2+ VPN Firewall Router

Chapter 3: Basic Installation

BiPAC 7402R2 can be configured with your web browser. The web browser is included as a standard application in the following operating systems: Linux, Mac OS, Windows 98/NT/2000/XP/Me, etc. The product provides a very easy and user-friendly interface for configuration.

PCs must have an Ethernet interface installed properly and be connected to BiPAC 7402R2 either directly or through an external repeater hub, and have TCP/IP installed and configured to obtain an IP address through a DHCP server or a fixed IP address that must be in the same subnet as BiPAC

7402R2. The default IP address of the router is 192.168.1.254 and the subnet mask is 255.255.255.0

(i.e. any attached PC must be in the same subnet, and have an IP address in the range of 192.168.1.1 to 192.168.1.253). The best and easiest way is to configure the PC to get an IP address automatically from BiPAC 7402R2 using DHCP. If you encounter any problems accessing the router’s web interface it

may also be advisable to uninstall any kind of software firewall on your PCs, as they can cause

problems accessing the 192.168.1.254 IP address of the router. Users should make their own decisions on how to best protect their network.

Please follow the steps below for your PC’s network environment installation. Before taking the first step, please check your PC’s network components. The TCP/IP protocol stack and Ethernet network adapter must be installed. If not, please refer to your Windows-related or other operating system manuals.

Any TCP/IP capable workstation can be used to communicate with or through the

BiPAC 7402R2. To configure other types of workstations, please consult the

manufacturer’s documentation.

Configuration

When you click this item, you get following sub-items to configure the ADSL router.

LAN, WAN, System, Firewall, VPN, QoS, Virtual Server, Time Schedule and Advanced

These functions are described below in the following sections.

LAN (Local Area Network)

There are seven items within the LAN section: Bridge Interface, Ethernet, Ethernet Client Filter, Port

Setting and DHCP Server.

Bridge Interface

You can setup member ports for each VLAN group under Bridge Interface section. From the example, two VLAN groups need to be created.

Ethernet: P1 (Port 1) Ethernet1: P2, P3 and P4 (Port 2, 3, 4) Please uncheck P2, P3, P4 from Ethernet VLAN port first.

Note: You should setup each VLAN group with caution. Each Bridge Interface is arranged in this order.

Bridge Interface VLAN Port (Always starts with)

Ethernet P1 / P2 / P3 / P4 Ethernet1 P2 / P3 / P4 Ethernet2 P3 / P4 Ethernet3 P4

Management Interface: To specify which VLAN group has possibility to do device management, like

doing web management.

Ethernet

Primary IP Address IP Address: The default IP on this router.

SubNetmask: The default subnet mask on this router. RIP: RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.

IP Alias

This function supports to create multiple virtual IP interfaces on this router. It helps to connect two or more local networks to the ISP or remote node. In this case, an internal router is not required.

IP Address: Specify an IP address on this virtual interface. SubNetmask: Specify a subnet mask on this virtual interface. Security Interface: Specify the firewall setting on this virtual interface. Internal: The network is behind NAT. All traffic will do network address translation when sending out to

Internet if NAT is enabled.

External: There is no NAT on this IP interface and connected to the Internet directly. Mostly it will be

used when providing multiple public IP addresses by ISP. In this case, you can use public IP address in local network which gateway IP address point to the IP address on this interface.

DMZ: Specify this network to DMZ area. There is no NAT on this interface.

Ethernet Client Filter

The Ethernet Client Filter supports up to 16 Ethernet network machines that helps you to manage your network control to accept traffic from specific authorized machines or can restrict unwanted machine(s) to access your LAN.

There are no pre-define Ethernet MAC address filter rules; you can add the filter rules to meet your requirements.

Ethernet Client Filter: Default setting is set to Disable.  Allowed: check to authorize specific device accessing your LAN by insert the MAC Address in the

space provided or click

 Blocked: check to prevent unwanted device accessing your LAN by insert the MAC Address in the

space provided or click

The maximum client is 16. The MAC addresses are 6 bytes long; they are presented only in

hexadecimal characters. The number 0 - 9 and letters a - f are acceptable.

Note: Follow the MAC Address Format xx:xx:xx:xx:xx:xx. Semicolon ( : ) must be included

Port Setting

This section allows you to configure the settings for the router’s Ethernet ports to solve some of the compatibility problems that may be encountered while connecting to the Internet, as well allowing users to tweak the performance of their network.

Port # Connection Type: Five options to choose from: Auto, 10M half-duplex, 10M full-duplex, 100M

half-duplex or 100M full-duplex. Sometimes, there are Ethernet compatibility problems with legacy

Ethernet devices, and you can configure different types to solve compatibility issues. The default is Auto,

which users should keep unless there are specific problems with PCs not being able to access your LAN.

IPv4 TOS priority Control (Advanced users): TOS, Type of Services, is the 2

octet of an IP packet.

Bits 6-7 of this octet are reserved and bit 0-5 are used to specify the priority of the packet.

This feature uses bits 0-5 to classify the packet’s priority. If the packet is high priority, it will flow first and will not be constrained by the Rate Limit. Therefore, when this feature is enabled, the router’s Ethernet switch will check the 2

octet of each IP packet. If the value in the TOS field matches the checked

values in the table (0 to 63), this packet will be treated as high priority.

Chapter 4: Configuration

BiPAC 7402R2 ADSL2+ VPN Firewall Router

DHCP Server

You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or enable the router’s DHCP relay functions. The DHCP protocol allows your router to dynamically assign IP addresses to PCs on your network if they are configured to obtain IP addresses automatically.

To disable the router’s DHCP Server, check Disabled and click Next, then click Apply. When the DHCP

Server is disabled you will need to manually assign a fixed IP address to each PCs on your network, and set the default gateway for each PCs to the IP address of the router (by default this is 192.168.1.254).

To configure the router’s DHCP Server, check DHCP Server and click Next. You can then configure

parameters of the DHCP Server including the IP pool (starting IP address and ending IP address to be allocated to PCs on your network), lease time for each assigned IP address (the period of time the IP address assigned will be valid), DNS IP address and the gateway IP address. These details are sent to

the DHCP client (i.e. your PC) when it requests an IP address from the DHCP server. Click Apply to enable this function. If you check “Use Router as a DNS Server”, the ADSL Router will perform the

domain name lookup, find the IP address from the outside network automatically and forward it back to the requesting PC in the LAN (your Local Area Network).

If you check DHCP Relay Agent and click Next, then you will have to enter the IP address of the DHCP

server which will assign an IP address back to the DHCP client in the LAN. Use this function only if advised to do so by your network administrator or ISP.

Click Apply to enable this function.

DNS

A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. On the Internet, every host has a unique and user-friendly name (domain name) such as www.helloworld.com

and an IP address. An IP address is a 32-bit number in the form of xxx.xxx.xxx.xxx, for example

192.168.1.254. You can think of an IP address as a telephone number for devices on the Internet, and the DNS will allow you to find the telephone number for any particular domain name. As an IP Address is hard to remember, the DNS converts the friendly name into its equivalent IP Address.

You can obtain a Domain Name System (DNS) IP address automatically if your ISP has provided it when

you logon, check the Enable box. Usually when you choose PPPoE or PPPoA as your WAN - ISP

protocol, the ISP will provide the DNS IP address automatically. You may leave the configuration field blank.

Alternatively, your ISP may provide you with an IP address of their DNS. If this is the case, you must enter the DNS IP address manually.

If you choose one of the other three protocols ─ RFC1483 Routed/Bridged and IPoA check with your ISP, it may provide you with an IP address for their DNS server. You must enter the DNS IP address if you set the DNS of your PC to the LAN IP address of this router.

System

There are six items within the System section: Time Zone, Remote Access, Firmware Upgrade,

Backup/Restore, Restart and User Management.

Time Zone

The router does not have a real time clock on board; instead, it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server outside your network. Choose your local time zone,

click Enable and click the Apply button. After a successful connection to the Internet, the router will

retrieve the correct local time from the SNTP server you have specified. If you prefer to specify an SNTP server other than those in the list, simply enter its IP address as shown above. Your ISP may provide an SNTP server for you to use.

Daylight Saving is also known as Summer Time Period. Many places in the world adapt it during

summer time to move one hour of daylight from morning to the evening in local standard time. Check

Automatic box to auto set your local time. Resync Period (in minutes) is the periodic interval the router will wait before it re-synchronizes the

router’s time with that of the specified SNTP server. In order to avoid unnecessarily increasing the load on your specified SNTP server you should keep the poll interval as high as possible – at the absolute minimum every few hours or even days.

You can choose not to enable Firewall, to add all filter rules by yourself, or enable the Firewall using preset filter rules and modify the port filter rules as required. The Packet Filter is used to filter packets based-on Applications (Port) or IP addresses.

There are four options when you enable the Firewall, they are:

 All blocked/User-defined: no pre-defined port or address filter rules by default, meaning that all

inbound (Internet to LAN) and outbound (LAN to Internet) packets will be blocked. Users have to add their own filter rules for further access to the Internet.

 High/Medium/Low security level: the predefined port filter rules for High, Medium and Low security

are displayed in Port Filters of Packet Filter.

Select either High, Medium or Low security level to enable the Firewall. The only difference between

these three security levels is the preset port filter rules in the Packet Filter. Firewall functionality is the same for all levels; it is only the list of preset port filters that changes between each setting. For more

detailed on level of preset port filter information, refer to Table 1: Predefined Port Filter.

If you choose of the preset security levels and then add custom filters, you may temporarily disable the firewall and recover your custom filter settings by re-selecting the same security level.

The “Block WAN Request” is a stand-alone function and not relate to whether security enable or

disable. Mostly it is for preventing any scan tools from WAN site by hacker.

Any remote user who is attempting to perform this action may result in blocking all the accesses to configure and manage of the device from the Internet.

Example: Configuring your firewall to allow for a publicly accessible web server on your LAN

The predefined port filter rule for HTTP (TCP port 80) is the same no matter whether the firewall is set to a high, medium or low security level. To setup a web server located on the local network when the firewall is enabled, you have to configure the Port Filters setting for HTTP.

As you can see from the diagram below, when the firewall is enabled with one of the three presets (Low/Medium/High), inbound HTTP access is not allowed which means remote access through HTTP to your router is not allowed.

Note: Inbound indicates accessing from Internet to LAN and Outbound is from LAN to the Internet

Intrusion Detection

BiPAC 7402R2 ADSL2+ VPN Firewall Router

The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and intrusion attempts

from the Internet. If the IDS function of the firewall is enabled, inbound packets are filtered and blocked depending on whether they are detected as possible hacker attacks, intrusion attempts or other connections that the router determines to be suspicious.

Blacklist: If the router detects a possible attack, the source IP or destination IP address will be added to

the Blacklist. Any further attempts using this IP address will be blocked for the time period specified as

the Block Duration. The default setting for this function is false (disabled). Some attack types are denied immediately without using the Blacklist function, such as Land attack and Echo/CharGen scan.

Intrusion Detection: If enabled, IDS will block Smurf attack attempts. Default is false.

Block Duration:

 Victim Protection Block Duration: This is the duration for blocking Smurf attacks. Default value is

600 seconds.

 Scan Attack Block Duration: This is the duration for blocking hosts that attempt a possible Scan

attack. Scan attack types include X’mas scan, IMAP SYN/FIN scan and similar attempts. Default value is 86400 seconds.

 DoS Attack Block Duration: This is the duration for blocking hosts that attempt a possible Denial of

Service (DoS) attack. Possible DoS attacks this attempts to block include Ascend Kill and WinNuke. Default value is 1800 seconds.

Max TCP Open Handshaking Count: This is a threshold value to decide whether a SYN Flood attempt

is occurring or not. Default value is 100 TCP SYN per seconds.

Max PING Count: This is a threshold value to decide whether an ICMP Echo Storm is occurring or not.

Default value is 15 ICMP Echo Requests (PING) per second.

Chapter 4: Configuration

BiPAC 7402R2 ADSL2+ VPN Firewall Router

Max ICMP Count: This is a threshold to decide whether an ICMP flood is occurring or not. Default value

is 100 ICMP packets per seconds except ICMP Echo Requests (PING).

For SYN Flood, ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event Log. It cannot

protect against such attacks.

URL Filtering

BiPAC 7402R2 ADSL2+ VPN Firewall Router

URL (Uniform Resource Locator – e.g. an address in the form of

http://www.example.com) filter rules allow you to prevent users on your network from accessing

particular websites by their URL. There are no pre-defined URL filter rules; you can add filter rules to meet your requirements.

http://www.abcde.com or

Enable/Disable: To enable or disable URL Filter feature. Block Mode: A list of the modes that you can choose to check the URL filter rules. The default is set to

Disabled.

 Disabled: No action will be performed by the Block Mode.  Always On: Action is enabled. URL filter rules will be monitoring and checking at all hours of the day.  TimeSlot1 ~ TimeSlot16: It is self-defined time period. You may specify the time period to check the

URL filter rules, i.e. during working hours. For setup and detail, refer to Time Schedule section.

Keywords Filtering: Allows blocking by specific keywords within a particular URL rather than having to

specify a complete URL (e.g. to block any image called “advertisement.gif”). When enabled, your specified keywords list will be checked to see if any keywords are present in URLs accessed to determine if the connection attempt should be blocked. Please note that the URL filter blocks web browser (HTTP) connection attempts using port 80 only.

Chapter 4: Configuration

BiPAC 7402R2 ADSL2+ VPN Firewall Router

For example, if the URL is http://www.abc.com/abcde.html, it will be dropped as the keyword “abcde” occurs in the URL.

Domains Filtering: This function checks the domain name only, not the IP address, in URLs accessed

against your list of domains to block or allow. If it is matched, the URL request will be sent (Trusted) or dropped (Forbidden). For this function to be activated, both check-boxes must be checked. The checking procedure is:

1. Check the domain in the URL to determine if it is in the trusted list. If yes, the connection attempt is sent to the remote web server.

2. If not, check if it is listed in the forbidden list, and if present then the connection attempt is dropped.

3. If the packet does not match either of the above two items, it is sent to the remote web server.

4. Please be note that the domain only should be specified, not the full URL. For example to block traffic to the URL request for trusted list, whilst the URL request for

www.sex.com, enter “sex” or “sex.com” instead of “www.sex.com”. In the example below,

www.abc.com will be sent to the remote web server because it is listed in the

www.sex or www.sex.com will be dropped, because sex.com

is in the forbidden list.

BiPAC 7402R2 ADSL2+ VPN Firewall Router

Restrict URL Features: This function enhances the restriction to your URL rules. Example: Andy wishes to disable all WEB traffic except for ones listed in the trusted domain, which

would prevent Bobby from accessing other web sites.

Andy selects both functions in the Domain Filtering and thinks that it will stop Bobby. But Bobby knows this function, Domain Filtering, ONLY disables all WEB traffic except for Trusted Domain, BUT not its IP address. If this is the situation, Block surfing by IP address function can be handy and helpful to Andy.

Now, Andy can prevent Bobby from accessing other sites.

 Block Java Applet: This function can block Web content that includes the Java Applet. It is to prevent

someone who wants to damage your system via standard HTTP protocol.

 Block surfing by IP address: Preventing someone who uses the IP address as URL for skipping Domains Filtering function. Activates only and if Domain Filtering enabled.

VPN (Virtual Private Networks)

Virtual Private Networks is ways to establish secured communication tunnels to an organization’s

network via the Internet. Your router supports three main types of VPN (Virtual Private Network), PPTP,

IPSec and L2TP.

PPTP (Point-to-Point Tunneling Protocol)

There are two types of PPTP VPN supported; Remote Access and LAN-to-LAN (please refer below for more information.). Click Create to configure a new VPN connection.

After you have created PPTP connection, account status will be displayed. (See example above).

 Enable / Disable: This function activates or deactivates the PPTP connection. To wish interrupting the tunnel, check Disable radio button and click Apply button to deactivate the connection.

Name: This is the user-defined name of the connection. Type: This refers to your router operates as a client or a server, Dialout or Dialin in respectively. Status: It informs your PPTP tunnel connection condition.

Chapter 4: Configuration

PPTP Connection - Remote Access

BiPAC 7402R2 ADSL2+ VPN Firewall Router

Connection Name: A user-defined name for the connection (e.g. “connection to office”). Type: Check Dial Out if you want your router to operate as a client (connecting to a remote VPN server,

e.g. your office server), check Dial In operates as a VPN server.

 When configuring your router as a Client, enter the remote Server IP Address (or Domain Name)

you wish to connection to.

 When configuring your router as a server, enter the Private IP Address Assigned to Dial in User

address.

Username: If you are a Dial-Out user (client), enter the username provided by your Host. If you are a

Dial-In user (server), enter your own username.

Password: If you are a Dial-Out user (client), enter the password provided by your Host. If you are a

Dial-In user (server), enter your own password.

PPP Authentication Type: Default is Auto if you want the router to determine the authentication type to

use, or else manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP (Password Authentication Protocol) if you know which type the server is using (when acting as a client), or else the authentication type you want clients connecting to you to use (when acting as a server). When using PAP, the password is sent unencrypted, whilst CHAP encrypts the password before sending, and also allows for challenges at different periods to ensure that an intruder has not replaced the client.

Data Encryption: Data sent over the VPN connection can be encrypted by an MPPE algorithm. Default is Auto, so that this setting is negotiated when establishing a connection, or else you can manually

Enable or Disable encryption. Key Length: The data can be encrypted by MPPE algorithm with 40 bits or 128 bits. Default is Auto, it

is negotiated when establishing a connection. 128 bit keys provide stronger encryption than 40 bit keys.

Mode: You may select Stateful or Stateless mode. The key will be changed every 256 packets when

you select Stateful mode. If you select Stateless mode, the key will be changed in each packet.

Idle Time: Auto-disconnect the VPN connection when there is no activity on the connection for a

predetermined period of time. 0 means this connection is always on.

 Single Address: The IP address of the local host.  Subnet: The subnet of the local network. For example, IP: 192.168.1.0 with netmask 255.255.255.0

specifies one class C subnet starting from 192.168.1.1 (i.e. 192.168.1.1 through to 192.168.1.254).  IP Range: The IP address range of the local network. For example, IP: 192.168.1.1, end IP:

192.168.1.10

Remote: Secure Gateway Address (or Domain Name): The IP address or hostname of the remote VPN device

that is connected and establishes a VPN tunnel.

Network: Set the IP address, subnet or address range of the remote network. Proposal: Select the IPSec security method. There are two methods of checking the authentication

information, AH (authentication header) and ESP (Encapsulating Security Payload). Use ESP for greater security so that data will be encrypted and authenticated. Using AH data will be authenticated but not encrypted.

Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered with in transmit. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm (SHA1) or NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower.

 MD5: A one-way hashing algorithm that produces a 128−bit hash.

Chapter 4: Configuration

BiPAC 7402R2 ADSL2+ VPN Firewall Router

 SHA1: A one-way hashing algorithm that produces a 160−bit hash. Encryption: Select the encryption method from the pull-down menu. There are several options, DES,

3DES, AES (128, 192 and 256) and NULL. NULL means it is a tunnel only with no encryption. 3DES

and AES are more powerful but increase latency.

 DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method.  3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption method.  AES: Stands for Advanced Encryption Standards, you can use 128, 192 or 256 bits as encryption

method.

Perfect Forward Secrecy: Choose whether to enable PFS using Diffie-Hellman public-key cryptography

to change encryption keys during the second phase of VPN negotiation. This function will provide better security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups.

Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters.

Both sides should use the same key. IKE is used to establish a shared security policy and authenticated keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key into both sides (router or hosts).

SA Lifetime: Specify the number of minutes that a Security Association (SA) will stay active before new

encryption and authentication key will be exchanged. There are two kinds of SAs, IKE and IPSec. IKE negotiates and establishes SA on behalf of IPSec, an IKE SA is used by IKE.

Phase 1 (IKE): To issue an initial connection request for a new VPN tunnel. The range can be from 5 to

15,000 minutes, and the default is 240 minutes.

Phase 2 (IPSec): To negotiate and establish secure authentication. The range can be from 5 to 15,000 minutes, and the default is 60 minutes.

A short SA time increases security by forcing the two parties to update the keys. However, every time the VPN tunnel re-negotiates, access through the tunnel will be temporarily disconnected.

PING for Keepalive: It is used to detect IPSec tunnel connection failure. Connection failure is defined as

abort or in NO response state. In such event Ping to Keepalive takes proper action to ensure the

connection quality of IPSec. PING to the IP: It is able to IP Ping the remote PC with the specified IP address and alert when the

connection fails. Once alter message is received, Router will drop this tunnel connection. Re-establish

of this connection is required. Default setting is 0.0.0.0 which disables the function. Internal: This sets the time interval between Pings to the IP function to monitor the connection status.

Default interval setting is 10 seconds. Time interval can be set from 0 to 3600 second, 0 second disables the function.

IPSec: Enable for enhancing your LT2P VPN security. Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered

with in transmit. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm (SHA1) or NONE. SHA-1 is more resistant to brute-force attacks than MD5, however it is slower.

 MD5: A one-way hashing algorithm that produces a 128−bit hash.  SHA1: A one-way hashing algorithm that produces a 160−bit hash.

Encryption: Select the encryption method from the pull-down menu. There are four options, DES, 3DES, AES and NONE. NONE means it is a tunnel only with no encryption. 3DES and AES are more powerful

but increase latency.

Perfect Forward Secrecy: Choose whether to enable PFS using Diffie-Hellman public-key cryptography

Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters.

Remote Host Name (Optional): Enter hostname of remote VPN device. It is a tunnel identifier from the

Remote VPN device matches with the Remote hostname provided. If remote hostname matches, tunnel will be connected; otherwise, it will be dropped.

Cautious: This is only when the router performs as a VPN server. This option should be used by advanced users only.

Local Host Name (Optional): Enter hostname of Local VPN device that is connected / establishes a VPN tunnel. As default, Router’s default Hostname is home.gateway.

Tunnel Authentication: This enables router to authenticate both the L2TP remote and L2TP host. This is only valid when L2TP remote supports this feature.

Secret: The secure password length should be 16 characters which may include numbers and

characters.
