The Route Table Configuration page is activated from the Main Menu page.
IMPORTANT
Do not operate a CDM-IP satellite link where both CDM-IP modems have a Default
Route to the satellite. For example, if both CDM-IP modems had this Route Table
entry:
IP Dest
Next Hop Type
0.0.0.0/0 Point-to-Point ToSat
In this setup, any traffic forwarded by a CDM-IP that did not have a valid IP host at
the remote LAN would then be resent by the remote CDM-IP. This traffic would
continue to be forwarded until the TTL expired. This “routing loop” will limit the
performance of the CDM-IP by wasting satellite bandwidth.
The Route Table Configuration page contains the following options/fields:
Menu Options/Fields Entry Description
Route001-Route008
(256)
(The 8 currently
displayed routes, up to
256 can be defined) 1-8 The Route Table allows a user to define how the packets
that the CDM-IP receives are routed. Defining an entry in
this table is similar to using the 'route add' command of
machines that support that command. For each route, the
user must define:
1. A name assigned by the user to reference the
route. The assigned name cannot contain any
whitespace and must be unique.
2. The destination address of an IP packet of
interest.
The number of network addresses that are governed by
the selected destination entry, i.e., subnet mask.
The Next Hop IP address. This is the IP where the packet
