A static route is a known, unchanging path from your LAN to another network
or subnet. You can set up to sixteen static routes on the Wireless Gateway. A
static route consists of the settings described below.
IP Address: This is the IP network address of an outside network or subnet.
When a machine on your LAN addresses a packet to any machine on this
outside destination network, the Wireless Gateway will route that packet
according to your Static Routing settings.
Subnet Mask: A subnet mask is necessary for the above IP network address.
Default Gateway: This is the IP address of the router or other gateway that
can best handle packets addressed to the destination network or subnet. It must
be a device on your LAN or on the network that the WAN port is connected
to — that is, there must not be any intervening “hops” between the Wireless
Gateway and the default gateway.
Interface: The Interface control is a drop-down list box with two options:
WAN and LAN. If the default gateway (see preceding) is networked to the
WAN port, leave this control set to its default setting, WAN; if the default
gateway is networked to one of the Wireless Gateway's LAN ports, set the
Interface control to LAN.
Dynamic Routing
The Wireless Gateway can perform dynamic routing — that is, it can
periodically exchange information with other routing devices to determine the
best paths for outward-bound packets. These exchanges are in a form called
the Routing Information Protocol (RIP). The Dynamic Routing section of the
Routing settings panel lets you control RIP operation on the Wireless
Gateway.
The Yes and No options turn dynamic routing on and off, respectively. As a
general rule, if a simple point-to-point connection to an ISP through the WAN
port is the only link to networks other than the local LAN, dynamic routing
should probably be turned off; otherwise, it might need to be turned on. The
correct setting must be determined by a technician familiar with the
networking environment in which the Wireless Gateway is installed. If a
setting of No is chosen here, the remaining controls in the Dynamic Routing
section have no effect.
