PPP Dial-up configuration

[apcastaneda]

I am configuring a PPP dial-up connection using a 2520 and a 2621. the 2520 is connected to the async modem. the 2621 has 2 ethernet ports, the one is connected to the 2520 and the other one is connected to our main network. after dial-up, the remote PC can ping the 2520 router including the ethernet port of the 2621 that is connected to the 2520. but i cannot ping to our main network. can i configure a router to set a default gateway to a remote PC? or any other way to solve the problem?

On the 2621 router you need add route to the ip addreses of modem connections on the 2520.

ip route a.a.a.a b.b.b.b c.c.c.c

where a.a.a.a - network address used for modem connections

b.b.b.b - mask

c.c.c.c - ip address of 2520s Ethernet interface

Thank you very much, but i had it already configured using rip. when i access the router 2520, i can ping all the stations in our main network. but the only problem is when i ping using the dial up connection. by the way, the remote PC is in the same network segment with the ethernet ports of the 2520 and 2621 routers.
