The Router supports PAP (Password Authentication Protocol) and CHAP (Challenge
Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP
is readily available on more platforms.
Use the drop-down list box to select an authentication protocol for outgoing calls.
Options are:
AUTO - Your Router accepts either CHAP or PAP when requested by this remote

MSCHAP - Your Router accepts MSCHAP only. MS-CHAP is the Microsoft version of
the CHAP.

service provider’s IP subnet to a single LAN computer.
• It lets only one computer on the LAN connect to the WAN.
• The public IP address from the ISP is forwarded through DHCP to the LAN
computer instead of being used on the WAN PPP interface.
• It disables NAT and the firewall.
• DHCP tells the LAN computer to use the gateway as the default gateway and
DNS server.
• The Router bridges IP packets between the WAN and LAN ports except packets
destined for the Router’s LAN IP address.

6.1 Virtual Servers
Click Advanced Setup > NAT > Virtual Servers to open the screen where you manage the list of
virtual server rules.
A virtual server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that
you can make visible to the outside world even though NAT makes your whole inside network
appear as a single computer to the outside world.
Many residential broadband ISP accounts do not allow you to run any server processes
(such as a Web or FTP server) from your location. Your ISP may periodically check for
servers and may suspend your account if it discovers any active services at your location. If
you are unsure, refer to your ISP.

Current UPNP
Rule Listing
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses
TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device
can dynamically join a network, obtain an IP address, convey its capabilities and learn
about other devices on the network. In turn, a device can leave a network smoothly
and automatically when it is no longer in use.
These are the rules the Router has created using UPnP.
External Port This is the external port number that identifies a service.
Internal This is the internal port number that identifies a service.
Client IP This is the IP address of the device for which the Router created the UPnP rule.
Protocol This is the protocol of the traffic for which the Router created the UPnP rule.

You may enter a single port number or a range of port numbers to be forwarded, and the local IP

port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can
support more than one service (for example both FTP and web service), it might be better to specify
a range of port numbers. You can allocate a server IP address that corresponds to a port or a range
of ports.

Chapter 6 Network Address Translation (NAT) 65
6.2 Port Triggering
Some services use a dedicated range of ports on the client side and a dedicated range of ports on
the server side. With regular port forwarding you set a forwarding port in NAT to forward a service
(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The
problem is that port forwarding only forwards a service to a single LAN IP address. In order to use
the same service on a different LAN computer, you have to manually replace the LAN computer's IP
address in the forwarding port with another LAN computer's IP address.
Chapter 6 Network Address Translation (NAT) 66
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take
turns using the service. The Router records the IP address of a LAN computer that sends traffic to
the WAN to request a service with a specific port number and protocol (a "trigger" port). When the
Router's WAN port receives a response with a specific port number and protocol ("open" port), the
Router forwards the traffic to the LAN IP address of the computer that sent the request. After that
computer’s connection for that service closes, another computer on the LAN can use the service in
the same manner. This way you do not need to configure a new IP address each time you want a
different LAN computer to use the application.
For example:
Figure 36 Trigger Port Forwarding Process: Example
1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a “trigger” port and causes the Router to record Jane’s computer IP address. The Router
associates Jane's computer IP address with the "open" port range of 6970-7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The Router forwards the traffic to Jane’s computer IP address.
5Only Jane can connect to the Real Audio server until the connection is closed or times out. The
Router times out in three minutes with UDP (User Datagram Protocol) or two hours with TCP/IP
(Transfer Control Protocol/Internet Protocol).
Click Advanced Setup > NAT > Port Triggering to manage your Router’s trigger port settings.

10.3 Policy Routing
Traditionally, routing is based on the destination address only and the Router takes the shortest
path to forward a packet. Policy routing allows the Router to override the default routing behavior
and alter the packet routing based on the policy defined by the network administrator. Policy-based
routing is applied to outgoing packets, prior to the normal routing.
You can use source-based policy routing to direct traffic from different users through different
connections or distribute traffic among multiple paths for load sharing.

universally supported but RIP version 2 carries more information. RIP version 1 is
probably adequate for most networks, unless you have an unusual network topology.

Chapter 14 Interface Grouping
14.1 Interface Grouping
By default, all LAN and WAN interfaces on the Router are in the same group and can communicate
with each other. Create interface groups to have the Router assign the IP addresses in different
domains to different groups. Each group acts as an independent network on the Router. This lets
devices connected to an interface group’s LAN interfaces communicate through the interface
group’s WAN or LAN interfaces but not other WAN or LAN interfaces.
You can manually add a LAN interface to a new group. Alternatively, you can have the Router
automatically add the incoming traffic and the LAN interface on which traffic is received to an
interface group when its DHCP Vendor ID option information matches one listed for the interface
group.
Use the LAN screen to configure the private IP addresses the DHCP server on the Router assigns to
the clients in the default and/or user-defined groups. If you set the Router to assign IP addresses
based on the client’s DHCP Vendor ID option information, you must enable DHCP server and
configure LAN TCP/IP settings for both the default and user-defined groups. Click Advanced Setup

15.1 IPv6inIPv4 (6RD)
Use IPv6 Rapid Deployment (6RD) when the local network uses IPv6 and the ISP has an IPv4
network. When the Router has an IPv4 WAN address and is configured to IPv4 only, you can enable
6RD to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.
The Router generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the
ISP’s Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The local network
can also use IPv4 services. The Router uses it’s configured IPv4 WAN IP to route IPv4 traffic to the
IPv4 Internet.
