4-10 Advanced Configuration of the Router
v3.1, June 2008
Configuring LAN TCP/IP Setup Parameters
The router is shipped preconfigured to use private IP addresses on the LAN side, and to act.as a
DHCP server. The router’s default LAN IP configuration is:
• LAN IP addresses—192.168.1.1
• Subnet mask—255.255.255.0
These addresses are part of the IETF-designated private address range for use in private networks,
and should be suitable in most applications. If your network has a requirement to use a different IP
addressing scheme, you can make those changes in this menu.
The LAN IP parameters are:
• IP Address. This is the LAN IP address of the router.
• IP Subnet Mask. This is the LAN Subnet Mask of the router. Combined with the IP address,
the IP Subnet Mask allows a device to know which other addresses are local to it, and which
must be reached through a gateway or router.
• RIP Direction. RIP (Router Information Protocol) allows a router to exchange routing
information with other routers. The RIP Direction selection controls how the router sends and
receives RIP packets. Both is the default.
– When set to Both or Out Only, the router will broadcast its routing table periodically.
– When set to Both or In Only, it will incorporate the RIP information that it receives.
– When set to None, it will not send any RIP packets and will ignore any RIP packets
received.
• RIP Version. This controls the format and the broadcasting method of the RIP packets that the
router sends. (It recognizes both formats when receiving.) By default, this is set for RIP-1.
– RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you
have an unusual network setup.
– RIP-2 carries more information. RIP-2B uses subnet broadcasting.
Note: If you change the LAN IP address of the router while connected through the
browser, you will be disconnected. You must then open a new connection to
the new IP address and log in again.
