Re: Routing a subnet

All of your examples work and are implemented at our site without any
problem. Problems arise when trying to route a network through a dialup
connection. (See my earlier post) This is where everything falls apart.
Any helpful suggestions??? I have talked to several support staff and they
all agree that this is a major problem and will be addressed in forthcoming
releases.

If possible, how would you suggest to configure the following scenario:

Portmaster - ether0 199.171.190.33/255.255.255.0

Dial In net- 204.178.205.96/255.255.255.248 (14 host subnet)

The host dialing in will be a Windows NT configured for TCP/IP and PPP. The
NT requires an IP on it's serial port to be of a different net/subnet than
the local network in order to route traffic. NT's don't pass RIP.

What radius and portmaster table entries would be needed to pass packets to
the NT when connected.

The 204.178.205 Class C may have subnets on many different portmasters (None
will be duplicated)

I have tried many different setups, and the only one that works is to set up
a series of static routes for the subnet to a specific portmaster, and at
the portmaster set up a route for every individual host on the subnet. I
must also turn off ether0's broadcasting of RIP as it will broadcast a route
for all of the class C, not just the subnet, which confuses the gateway routers.
