IP Address-- The IP address specifies the basic IP address to route.
IP Mask-- The Subnet Mask which defines the basic class of IP
addresses that will be routed. Clicking the Select button displays the IP
Mask List, which the shows the IP Masks that can be used as public or
private IP masks for IP routing. The list consists of all possible subnet
masks, and represents the range of addresses that will be translated.
Interface-- An interface number specifies where the IP subnet is
attached.
Add Indirect IP Routes
The Add Indirect IP Route screen is used to add indirect IP routes.
When the base station needs to send IP packets between IP subnets
which are not directly connected to one of its interfaces (i.e., not on the
same network segment), it must have an indirect route for sending those
packets.
An indirect route consists of:
An IP Address which specifies the basic IP address to route,
A Subnet Mask which defines the class of IP addresses that will be
routed,
A Target Router that will relay the IP packet, and
A Cost value, which specifies the number of "hops" required for the
indirect route.
When an IP packet addressed to a system on the indirectly routed subnet
arrives at the base station, the base station will route it over the interface
specified to the Target Router to be further routed.
