Getting Started

The default settings are sufficient for many small businesses. Network demands or your Internet Service Provider (ISP) might require modification of the settings. To use the web interface, you need a PC with Internet Explorer (version 6 and higher), Firefox, or Safari (for Mac).

To launch the web interface:

STEP 1 Connect a PC to a numbered LAN port on the device. If the PC is configured to

become a DHCP client, an IP address in the 192.168.1.x range is assigned to the PC.

STEP 2 Start a web browser.

STEP 3 In the address bar, enter the default IP address of the device, 192.168.1.1. The

browser might issue a warning that the web site is untrusted. Continue to the web site.

STEP 4 When the login page appears, enter the default user name cisco and the default

password cisco (lowercase).

STEP 5 Click Login. The System Summary page appears. Check the Port Activity to see

if a WAN connection is enabled. If not, continue to the next step.

STEP 6 To use the setup wizard to configure your Internet connection, click Setup Wizard

on the System Summary page. Or click Wizard in the navigation tree and in the Basic Setup section, click Launch Now. Follow the on-screen instructions.

If your web browser displays a warning message about the pop-up window, allow the blocked content.

Features of the User Interface

Troubleshooting Tips

If you have trouble connecting to the Internet or the web-based web interface:

• Verify that your web browser is not set to Work Offline.

• Check the local area network connection settings for your Ethernet adapter.

The PC should obtain an IP address through DHCP. Alternatively, the PC can have a static IP address in the 192.168.1.x range with the default gateway set to 192.168.1.1 (the default IP address of the device).

• Verify that you entered the correct settings in the Wizard to set up your

Internet connection.

• Reset the modem and the device by powering off both devices. Next,

power on the modem and let it sit idle for about 2 minutes. Then power on the device. You should now receive a WAN IP address.

• If you have a DSL modem, ask your ISP to put the DSL modem into bridge

mode.

Features of the User Interface

The user interface is designed to make it easy for you to set up and manage your device.

(Port) Forwarding

Port forwarding allows public access to services on network devices on the LAN by opening a specific port or port range for a service, such as FTP. Port triggering opens a port range for services such as Internet gaming that use alternate ports to communicate between the server and the LAN host.

Configuring Port Forwarding

When users make requests for services on your network, the device forwards those requests to your servers based on the port forwarding parameters. Any services not specified are denied access. For example, when port number 80 (HTTP) is forwarded to the IP address 192.168.1.2, all HTTP requests on the interface are forwarded to 192.168.1.2. All other traffic is denied, unless specifically allowed by another entry.

Use this function to establish a web server or FTP server. Make sure that you enter a valid IP address. (To run an Internet server, it might be necessary to use a static IP address.) For added security, outside users are able to communicate with the server, but they are not allowed to connect to network devices.

Port Address Translation

Port Address Translation (PAT) is an extension of Network Address Translation (NAT) that permits multiple devices on a LAN to be mapped to a single public IP address to conserve IP addresses.

PAT is similar to port forwarding except that an incoming packet with destination port (external port) is translated to a packet different destination port (an internal port). The Internet Service Provider (ISP) assigns a single IP address to the edge device. When a computer logs on to the Internet, this device assigns the client a port number that is appended to the internal IP address, giving the computer a unique IP address.

If another computer logs on the Internet, this device assigns it the same public IP address, but a different port number. Although both computers are sharing the same public IP address, this device knows which computer to send its packets, because the device uses the port numbers to assign the packets the unique internal IP address of the computers.

To add or edit PAT:

STEP 1 To add a service, click Add in the Port Address Translation table.

One-to-one NAT creates a relationship that maps a valid WAN IP address to LAN IP addresses that are hidden from the WAN (Internet) by NAT. This protects the LAN devices from discovery and attack.

For best results, reserve IP addresses for the internal resources that you want to reach through one-to-one NAT.

You can map a single LAN IP address or a range of IP addresses to an external range of WAN IP addresses of equal length (for example, three internal addresses and three external addresses). The first internal address is mapped to the first external address, the second IP internal IP address is mapped to the second external address, and so on.

Advanced Routing

This feature enables dynamic routing and adds static routes to the routing table for IPv4 and IPv6.

To view the routing table, click View Routing Table. Click Refresh to update the data. Click Close to close the pop-up window.

Configuring Dynamic Routing

Dynamic routing constructs routing tables automatically, based on information carried by routing protocols, and allowing the network to act nearly autonomously in avoiding network failures and blockages.

To configure IPv4 dynamic routing by using Routing Information Protocol (RIP), click the IPv4 tab.

To configure IPv6 dynamic routing by using Routing Information Protocol next generation (RIPng), click the IPv6 tab.

Configuring IPv4 Dynamic Routing

STEP 1 Choose the Working Mode:

• Gateway—Choose this mode if this device is hosting the network

connection to the Internet. This is the default setting.

• Router—Choose this mode if the device is on a network with other routers

and another device is the network gateway to the Internet or this network is not connected to the Internet. In Router mode, Internet connectivity is available to the network devices only if you have another router that functions as the Gateway. Since firewall protection is provided by the gateway, disable this device firewall.

STEP 2 Enable RIP to allow this device to exchange its routing information automatically

with other routers, and to dynamically adjust its routing tables as network changes occur. The default setting is Disabled. If you enable this feature, also configure the following settings:

• Receive RIP versions—Select the RIP protocol for receiving network data:

None, RIPv1, RIPv2, or Both RIP v1 and v2.

RIPv1 is a class-based routing version. It does not include subnet

information and therefore does not support variable length subnet masks

Cisco RV320/RV325 Administration Guide 41

Setup

Advanced Routing

(VLSM). RIPv1 also lacks support for router authentication, making it vulnerable to attacks. RIPv2 carries a subnet mask and supports password authentication security.

• Transmit RIP versions—Select the RIP protocol for transmitting network

data: None, RIPv1, RIPv2 - Broadcast, or RIPv2 - Multicast.

RIPv2 - Broadcast (recommended) broadcasts data in the entire subnet. RIPv2 - Multicast sends data to multicast addresses. RIPv2 - Multicast also

helps to avoid unnecessary load by multicasting routing tables to adjacent routers rather than broadcasting to the entire network.

STEP 3 Click Save.

Configuring IPv6 Dynamic Routing

The IPv6 tab is available if you enabled Dual-Stack IP on the Setup > Network page.

To enable RIPng, check the RIPng box.

Configuring Static Routing

Static routing can be configured for IPv4 or IPv6. These are routes that do not age out of the routing table. You can enter up to 30 routes.

To configure a static route, click Add or select an entry and click Edit:

• Destination IP—Subnetwork address of the remote LAN segment. For a

Class C IP domain, the network address is the first three fields of the Destination LAN IP; the last field should be 0.

• Subnet Mask (IPv4 only)—Subnetwork mask used on the destination LAN

IP domain. For Class C IP domains, the subnet mask is typically

255.255.255.0.

• Prefix Length (IPv6 only)—IPv6 prefix length.

• Default Gateway—IP address of the router of last resort.

• Hop Count—Maximum number of nodes or hops (the maximum is 15 hops)

that a packet passes through before being discarded. A node is any device on the network, such as a switch or router.

• Interface—Interface to use for this route.

DHCP

Dynamic Host Configuration Protocol (DHCP) is a network protocol that is used to configure network devices to communicate on an IP network. A DHCP client uses the DHCP protocol to acquire configuration information, such as an IP address, a default route, and one or more DNS server addresses from a DHCP server. The DHCP client then uses this information to configure its host. Once the configuration process is complete, the host is able to communicate on the Internet.

The DHCP server maintains a database of available IP addresses and configuration information. When it receives a request from a client, the DHCP server determines the network to which the DHCP client is connected, and allocates an IP address or prefix appropriate for the client, and sends configuration information appropriate for that client.

The DHCP server and DHCP client must be connected to the same network link. In larger networks, each network link contains one or more DHCP relay agents. These DHCP relay agents receive messages from DHCP clients and forward them to DHCP servers. DHCP servers send responses back to the relay agent, and the relay agent then sends these responses to the DHCP client on the local network link.

DHCP servers typically grant IP addresses to clients for a limited interval called a lease. DHCP clients are responsible for renewing their IP address before that interval has expired, and must stop using the address once the interval has expired, if they have not been able to renew it.

DHCP is used for IPv4 and IPv6. While both versions serve the same purpose, the details of the protocol for IPv4 and IPv6 are sufficiently different that they should be considered separate protocols.

Cisco RV320/RV325 Administration Guide 45

DHCP Setup

DHCP

DHCP Setup

DHCP Setup configures DHCP for IPv4 or IPv6. It also allows some devices to download their configuration from a TFTP server. When a device starts, if it does not have both the IP address and TFTP server IP address pre configured, it sends a request with Option 66, 67, and 150 to the DHCP server to obtain this information.

DHCP Option 150 is Cisco proprietary. The IEEE standard that similar to this requirement is Option 66. Like Option 150, Option 66 is used to specify the Name of the TFTP server. Option 67 provides the boot file name.

Option 82 (DHCP relay agent information option) enables a DHCP relay agent to include information about itself when forwarding client-originated DHCP packets to a DHCP server. The DHCP server can use this information to implement IP addressing or other parameter-assignment policies.

To set up DHCP IPv4, click the IPv4 tab. To set up DHCP IPv6, click the IPv6 tab.

Configuring DHCP for IPv4

To configure DHCP for IPv4:

STEP 1 Choose VLAN or Option 82.

STEP 2 If you choose Option 82, add circuit IDs by using DHCP > Option 82. Those circuit

IDs are then listed in the Circuit ID drop-down menu.

If you choose VLAN, select the VLAN from the VLAN ID menu and enter:

• Device IP Address—Management IP address.

• Subnet Mask—Management IP subnetwork mask.

STEP 3 Select the DHCP Mode:

• Disable—Disables DHCP on this device. There are no additional parameters

to complete.

• DHCP Server—Communicates the client DHCP requests to the device

• Client Lease Time—Amount of time in minutes that a network user is

allowed to connect to the router with the current IP address. Valid values are 5 to 43200 minutes. The default is 1440 minutes (equal to 24 hours).

• Range Start and Range End—Starting and ending IP addresses that create

a range of IP addresses that can be assigned dynamically. The range can be up to the maximum number of IP addresses that the server can assign without overlapping features such as PPTP and SSL VPN . Do not include this device LAN IP address in this dynamic IP range. For example, if the router uses the default LAN IP address, 192.168.1.1, the starting value must be

192.168.1.2 or greater.

• DNS Server—DNS service type; where the DNS server IP address is

acquired.

• Static DNS 1 and Static DNS 2—Static IP address of a DNS Server.

(Optionally) if you enter a second DNS server, the device uses the first DNS server to respond to a request.

• WINS—Optional IP address of a Windows Internet Naming Service (WINS)

server that resolves NetBIOS names to IP addresses. If you do not know the IP address of the WINS server, use the default, 0.0.0.0.

Using the Static IP List to Block Devices

The Static IP list can be used to control access to your network.

To block access by devices that are not on the list or do not have the correct IP address:

• Block MAC address on the list with wrong IP address—Check this box to

prevent a device from accessing your network if its IP address has been changed. For example, if you assigned a static IP address of 192.168.1.100 and someone configures the device to use 192.168.149, the device is not allowed to connect to your network. This discourages users from changing their device IP addresses without your permission. Uncheck the box to allow access regardless of the current IP address assignment.

• Block MAC address not on the list—Check this box to block access from

devices that are not included in the Static IP list. This prevents unknown devices from accessing your network. Uncheck the box to allow access by any device that is configured with an IP address in the correct range.

DNS Local Database

Domain Name Service (DNS) matches a domain name to its routable IP address. You can set up a DNS Local Database that enables the device to act as a local DNS server for commonly used domain names. Using a local database might be faster than using an external DNS server. If a requested domain name is not found in the local database, the request is forwarded to the DNS server that is specified on the

Setup Network > WAN Setting page.

If you enable this feature, you also must configure the client devices to use the device as the DNS server. By default, Windows computers are set to obtain a DNS server address automatically from the default gateway.

To change the TCP/IP connection settings, for example, on a PC running Windows, go to the Local Area Connection Properties > Internet Protocol > TCP/IP Properties window. Choose Use the following DNS server address, and enter the LAN IP address of the router as the Preferred DNS Server. For more information, refer to the documentation for the client that you are configuring.

Router Advertisement (IPv6)

The RADVD (Router Advertisement Daemon) is used for IPv6 auto-configuration and routing. When enabled, messages are sent by the router periodically and in response to solicitations. A host uses the information to learn the prefixes and parameters for the local network. Disabling this feature effectively disables autoconfiguration, requiring manual configuration of the IPv6 address, subnet prefix, and default gateway on each device.

This page is available if you enabled Dual-Stack IP on the Setup Network page. If you did not do so, a message appears when you try to open this page.

To Enable Router Advertisement, check the box and complete the other fields:

• Advertise Mode—Choose one of the following options:

- Unsolicited Multicast—Send Router Advertisement messages to all

interfaces in the multicast group. This option is the default setting. Also enter the Advertisement Interval; the interval at which Router Advertisement messages are sent. Enter any value between 10 and 1800 seconds. The default is 30 seconds.

- Unicast only—Send Router Advertisement messages only to well-

known IPv6 addresses.

DHCP

Router Advertisement (IPv6)

• RA Flags—Determines whether or not hosts can use DHCPv6 to obtain IP

addresses and related information. The options are:

- Managed—Hosts use an administered, stateful configuration protocol

(DHCPv6) to obtain stateful addresses and other information through DHCPv6.

- Other—Uses an administered, stateful configuration protocol (DHCPv6)

to obtain other, non-address information, such as DNS server addresses.

• Router Preference—High, Medium, or Low preference metric is used in a

network topology where multi-homed hosts have access to multiple routers. This metric helps a host to choose an appropriate router. If two routers are reachable, the one with the higher preference is chosen. These values are ignored by hosts that do not implement router preference. The default setting is High.

• MTU—Size of the largest packet that can be sent over the network. The

MTU (Maximum Transmission Unit) is used in Router Advertisement messages to ensure that all nodes on the network use the same MTU value when the LAN MTU is not well-known. The default setting is1500 bytes, which is the standard value for Ethernet networks. For PPPoE connections, the standard is 1492 bytes. Unless your ISP requires a different setting, this setting should not be changed.

• Router Lifetime—Time in seconds that the Router Advertisement

messages exist on the route. The default is 3600 seconds.

To add a new subnet, click Add and enter an IPv6 Address, Prefix Length, and Lifetime.

When you restart from the Restart page, the router sends out your log file (if logging is enabled) before the device is reset. The device parameters are retained.

To restart the device, click Restart Router.

Backup and Restore

Configuration files can be imported, exported, and copied. The router has two managed configuration files, startup and mirror. The device loads the startup file from memory when it boots up into the running configuration and copies the startup file to the mirror file. Thus, the mirror file contains the last known valid configuration.

If the Startup configuration file is corrupted or fails for any reason, the mirror configuration file is used. The router automatically copies the startup configuration to the mirror configuration after 24 hours of running in stable condition (no reboots and no configuration changes within the 24-hour period).

Firewall

The primary objective of a firewall is to control the incoming and outgoing network traffic by analyzing the data packets and determining whether it should be allowed through or not, based on a predetermined rule set. A network firewall builds a bridge between an internal network that is assumed to be secure and trusted and another network, usually an external (inter)network such as the Internet that is assumed not to be secure and untrusted.

General

General firewall controls manage the features typically used by Internet browsers and applications.

Enabling Firewall Features

To enable the Firewall, check Enable. The following firewall features can be enabled or disabled as needed:

• SPI (Stateful Packet Inspection)—Monitors the state of network

connections (such as TCP streams, UDP communication) traveling across it. The firewall distinguishes legitimate packets for different types of connections. Only packets matching a known active connection are allowed by the firewall; others are rejected.

• DoS (Denial-of-service )—Detects attempts to cause a server overload. In

general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.

• Block WAN Request—Drops TCP requests and ICMP packets.

• Remote Management—Allows remote management of the device when

enabled. The port is 443 by default. It can be changed to any user-defined port. The string will be https://<wan-ip>:<remote-management-port>

Cisco RV320/RV325 Administration Guide 75

Firewall

Access Rules

• Multicast Pass Through—Allows multicast messages to pass through the

device.

• HTTPS—Hypertext Transfer Protocol Secure is a communications protocol

for secure communication over a computer network, with especially wide deployment on the Internet.

• SSL VPN—Allows SSL VPN connections.

• SIP ALG—Application layer gateway that augments a firewall or NAT. It

allows customized NAT traversal filters to be plugged into the gateway to support address and port translation for SIP control/data protocols.

• UPnP—Universal Plug and Play is a set of networking protocols that

permits network devices, such as personal computers, printers, Internet gateways, Wi-Fi access points, and mobile devices, to seamlessly discover each other's presence on the network and establish functional network services for data sharing and communications.

VPN

A VPN is a connection between two endpoints in different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This tunnel establishes a private network that can send data securely by using industry-standard encryption and authentication techniques to secure the data sent.

Summary

This feature displays general information about the VPN tunnel settings. The device supports up to 100 tunnels. The Virtual IP Range is reserved for EasyVPN users or VPN clients that connect to this device with the Mode Configuration option (described in Advanced Settings for IKE with Preshared Key and IKE

with Certificate) enabled.

To set a range of IP addresses to be used for VPN tunnels, click Edit and enter the following parameters:

Gateway to Gateway

In a site-to-site or gateway-to-gateway VPN, the local router at one office connects to a remote router through a VPN tunnel. Client devices can access network resources as if they were all at the same site. This model can be used for multiple users at a remote office.

A successful connection requires that at least one of the routers to be identifiable by a static IP address or a Dynamic DNS hostname. Alternatively, if one router has only a dynamic IP address, you can use any email address as authentication to establish the connection.

The two ends of the tunnel cannot be on the same subnet. For example, if the Site A LAN uses the 192.168.1.x/24 subnet, Site B can use 192.168.2.x/24.

To configure a tunnel, enter corresponding settings (reversing local and remote) when configuring the two routers. Assume that this router is identified as Router A. Enter its settings in the Local Group Setup section; enter the settings for the other router (Router B) in the Remote Group Setup section. When you configure the other router (Router B), enter its settings in the Local Group Setup section, and enter the Router A settings in the Remote Group Setup section.

IPSec Setup

For encryption to be successful, the two ends of a VPN tunnel must agree on the methods of encryption, decryption, and authentication. Enter exactly the same settings on both routers.

Enter the settings for Phase 1 and Phase 2. Phase 1 establishes the preshared keys to create a secure authenticated communication channel. In Phase 2, the IKE peers use the secure channel to negotiate Security Associations on behalf of other services such as IPsec. Be sure to enter the same settings when configuring other router for this tunnel.

• Phase 1 / Phase 2 DH Group—DH (Diffie-Hellman) is a key exchange

protocol. There are three groups of different prime key lengths: Group 1 768 bits, Group 2 - 1,024 bits, and Group 5 - 1,536 bits. For faster speed and lower security, choose Group 1. For slower speed and higher security, choose Group 5. Group 1 is selected by default.

• Phase 1 / Phase 2 Encryption—Method of encryption for this phase: DES,

3DES, AES-128, AES-192, or AES-256. The method determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is more secure.

• Phase 1 / Phase 2 Authentication—Method of authentication for this

phase: MD5 or SHA1. The authentication method determines how the ESP (Encapsulating Security Payload Protocol) header packets are validated. MD5 is a one-way hashing algorithm that produces a 128-bit digest. SHA1 is a one-way hashing algorithm that produces a 160-bit digest. SHA1 is recommended because it is more secure. Make sure that both ends of the VPN tunnel use the same authentication method.

• Phase 1 / Phase 2 SA Life Time—Length of time a VPN tunnel is active in

this phase. The default value for Phase 1 is 28800 seconds. The default value for Phase 2 is 3600 seconds.

Cisco RV320/RV325 Administration Guide 87

• Perfect Forward Secrecy—When Perfect Forward Secrecy (PFS) is

enabled, IKE Phase 2 negotiation generates 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. Check the box to enable this feature, or uncheck the box to disable this feature. This feature is recommended.

• Preshared Key—Preshared key to use to authenticate the remote IKE peer.

You can enter up to 30 keyboard characters or hexadecimal values, such as My_@123 or 4d795f40313233 (' ' " \ are not supported). 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.

• Minimum Preshared Key Complexity—Check the Enable box to enable

the Preshared Key Strength Meter.

• Preshared Key Strength Meter—When you enable Minimum Preshared

Key Complexity, this meter indicates the preshared key strength. As you enter a preshared key, colored bars appear. The scale goes from red (weak) to yellow (acceptable) to green (strong).

TIP Enter a complex preshared key that includes more than eight characters,

upper- and lowercase letters, numbers, and symbols such as -*^+=.

Advanced Settings for IKE with Preshared Key and IKE with Certificate

For most users, the basic settings should suffice; advanced users can click Advanced to display the advanced settings. If you change the Advanced settings on one router, also enter the settings on the other router.

• Aggressive Mode—Two modes of IKE SA negotiation are possible: Main

If the Remote Security Gateway Type is one of the Dynamic IP types, Aggressive Mode is required. The box is checked automatically, and this setting cannot be changed.

• Compress (Support IP Payload Compression Protocol (IP Comp))—A

protocol that reduces the size of IP datagrams. Check the box to enable the router to propose compression when it initiates a connection. If the responder rejects this proposal, then the router does not implement compression. When the router is the responder, it accepts compression, even if compression is not enabled. If you enable this feature for this router, also enable it on the router at the other end of the tunnel.

• Keep-Alive—Attempts to reestablish the VPN connection if it is dropped.

• AH Hash Algorithm—Authentication Header (AH) protocol describes the

packet format and default standards for packet structure. When AH is the security protocol, protection is extended forward into the IP header to verify the integrity of the entire packet. Check the box to use this feature and select an authentication method: MD5 or SHA1. MD5 produces a 128-bit digest to authenticate packet data. SHA1 produces a 160-bit digest to authenticate packet data. Both sides of the tunnel should use the same algorithm.

• NetBIOS Broadcast—Broadcast messages used for name resolution in

Windows networking to identify resources such as computers, printers, and file servers. These messages are used by some software applications and Windows features such as Network Neighborhood. LAN broadcast traffic is typically not forwarded over a VPN tunnel. However, you can check this box to allow NetBIOS broadcasts from one end of the tunnel to be rebroadcast to the other end.

Cisco RV320/RV325 Administration Guide 89

• NAT Traversal—Network Address Translation (NAT) enables users with

private LAN addresses to access Internet resources by using a publicly routable IP address as the source address. However, for inbound traffic, the NAT gateway has no automatic method of translating the public IP address to a particular destination on the private LAN. This issue prevents successful IPsec exchanges. If your VPN router is behind a NAT gateway, check this box to enable NAT traversal. The same setting must be used on both ends of the tunnel.

• Dead Peer Detection (DPD)—Sends periodic HELLO/ACK messages to

check the status of the VPN tunnel. This feature must be enabled on both ends of the VPN tunnel. Specify the interval between HELLO/ACK messages in the Interval field.

• Extended Authentication—Uses an IPsec host username and password to

authenticate the VPN clients or it uses the user database found in User Management. Both IPSec host and edge device must enable Extended Authentication. To use the IPsec Host, click the radio button and enter the User Name and Password. To use the Edge Device, click the radio button and select the database from the drop-down menu. To add or edit the database, click Add/Edit to display the User Management window.

• Tunnel Backup—When DPD determines that the remote peer is unavailable,

this feature enables the router to reestablish the VPN tunnel by using either an alternative IP address for the remote peer or an alternative local WAN interface. Check the box to enable this feature and enter the following settings. This feature is available only if Dead Peer Detection is enabled.

- Remote Backup IP Address—Alternative IP address for the remote

peer, or reenter the WAN IP address that was already set for the remote gateway.

- Local Interface—WAN interface to use to reestablish the connection.

- VPN Tunnel Backup Idle Time—When the router boots up and the

primary tunnel is not connected within the specified period, the backup tunnel is used. The default idle time is 30 seconds.

• Split DNS—Sends some of the DNS requests to one DNS server and other

DNS requests to another DNS server, based on specified domain names. When the router receives an address resolution request from client, it inspects the domain name. If it matches one of the domain names in the Split DNS settings, it passes the request to the specified DNS server. Otherwise, the request is passed to the DNS server that is specified in the WAN interface settings.

DNS Server 1 and DNS Server 2—IP address of the DNS server to use for the specified domains. Optionally, specify a secondary DNS server in the

IPSec Setup

For encryption to be successful, the two ends of a VPN tunnel must agree on the methods of encryption, decryption, and authentication. Enter exactly the same settings on both routers.

Enter the settings for Phase 1 and Phase 2. Phase 1 establishes the preshared keys to create a secure authenticated communication channel. In Phase 2, the IKE peers use the secure channel to negotiate Security Associations for other services such as IPsec. Be sure to enter the same settings when configuring other routers for this tunnel.

• Phase 1 / Phase 2 DH Group—DH (Diffie-Hellman) is a key exchange

• Phase 1 / Phase 2 Encryption—Method of encryption for this phase: DES,

3DES, AES-128, AES-192, or AES-256. The method determines the length of the key used to encrypt or decrypt ESP packets. AES-256 is recommended because it is more secure.

• Phase 1 / Phase 2 Authentication—Method of authentication for this

• Phase 1 / Phase 2 SA Life Time—Length of time a VPN tunnel is active in

this phase. The default value for Phase 1 is 28800 seconds. The default value for Phase 2 is 3600 seconds.

• Preshared Key—Preshared key to use to authenticate the remote IKE peer.

You can enter up to 30 keyboard characters or hexadecimal values, such as My_@123 or 4d795f40313233. Both ends of the VPN tunnel must use the same Preshared Key. We recommend that you change the Preshared Key periodically to maximize VPN security.

• Preshared Key Strength Meter—When you enable Minimum Preshared

Key Complexity, this meter indicates the preshared key strength. As you enter a preshared key, colored bars appear. The scale goes from red (weak) to yellow (acceptable) to green (strong).

TIP Enter a complex preshared key that includes more than eight characters,

upper- and lowercase letters, numbers, and symbols such as -*^+= (' ' " \ are not supported).

Advanced Settings for IKE with Preshared Key and IKE with Certificate

• Aggressive Mode—Two modes of IKE SA negotiation are possible, Main

Mode and Aggressive Mode. If network security is preferred, Main Mode is recommended. If network speed is preferred, Aggressive Mode is recommended. Check this box to enable Aggressive Mode, or uncheck the box to use Main Mode. If the Remote Security Gateway Type is one of the Dynamic IP types, Aggressive Mode is required. The box is checked automatically, and this setting cannot be changed.

enable Point-to-Point sessions by using the Internet at Layer 2.

PPTP Server

Up to 10 PPTP (Point-to-Point Tunneling Protocol) VPN tunnels can be enabled for users who are running PPTP client software. For example, in Windows XP or 2000, a user opens the Network Connections panel and creates a new connection. In the wizard, the user selects the option to create a connection to the workplace by using a Virtual Private Network connection. The user must know the WAN IP address of this device. For more information, refer to the documentation or help files for your operating system.

To enable the PPTP server and allow PPTP VPN tunnels, check the Enable box and enter the range:

Range Start and Range End—Range of LAN address to assign to the PPTP VPN clients. The LAN IP address range for PPTP VPN clients should be outside of the normal DHCP range of the router.

The Connection Table shows the tunnels in use. PPTP user accounts are added in the User Management window (select Unassigned in the Group column).
