Routing a Class C through a modem

I'm sure this question has been answered many times,
but I can't seem to get this to work.

This is probably a simple routing question. This
works with a Cisco 2511, with secondary
statements and static routes in my 2501 and 2511. Mixed
with dynamic routing on the 2511 modem port along with
a peer default ip address.

In general how does one route a class C through a port
on the Portmaster? Where the portmaster is on a seperate
class C from the one being routed?

Specifically:

I'd like to do this with a pm25 and a Cisco 4500, but can't seem to
get the routing correct. What statements would I
need to add to the Cisco 4500, and Livingston PM25 to
route 204.177.135.0 through a portmaster with a 204.177.131.54
address.

All network addresses have the prefix 204.177.

-------------------------------
| CISCO 4500 6 port ethernet |
---[]---[]---[]---[]---[]---[]-
.130 .131 .132 .133 .134 .135

The 204.177.130. goes to the radius server.

The pm25 is on the 131 network

modem -> to 204.177.135.0 network (204.177.135.65
| is the ip on the 135 router)
----------------{ }---
| Portmaster 25 |
-----[]----------------
204.177.131.57 -> Ethernet

How do I route 204.177.135.0 through this one modem port?

I hope this is clear.
Thank you,

Ed
