Internet access for remote site over dedicated T1 line w/ Cisco 1720s

Please Please Please help!!!!!

Site A has a Dedicated T1 Point-to-Point with Site B using cisco 1720 routers. Site A also has a cisco 2501 router for internet access. Site A can get to the internet. I want site be to be able to use Site A's connection to the internet through the dedicated T1. Check the specs and tell me what I'm doing wrong:

Site A: cisco 1720- WAN Serial0= LAN Ethernet=

cisco 2501- LAN ethernet=

Site B: cisco 1720- WAN Serial0= LAN ethernet=

Now here's the real treachery. My SIte B router can only see (ping)the Site A cisco 1720. My Site B clients, though can ping and see any clients in site A but not the 2501 router in Site A. I've already changed the default route to all possible options...Nothing. All my traceroutes from Site B router stop at My firewall has given free roaming privileges to Site B (the 10... and 192...)...Still nothing. What am I doing wrong? Am I missing a protocol? something not enabled? If more info is needed please let me know. I'm drowning here. I have decent working knowledge of networks but my cisco router configuring is still young. Please, explain like I'm slow. Thanks in advance

Loading thread data ...

first are you using any dynamic routing protocol like rip,ospf anything ?

If not and you dont intend to then try this on site a 2501 configure a static route ip route

next configure on site B ip route

on the b site use as your default gateway.

what i think is happening is that may be the 2501 router does not know how to get to site b . in other words 2501 does not have a route to site b. you can confirm this by looking at your routing table command is show ip route so i put a static route on 2501 to send all the traffic to site b to the 1720 at site A

next on B site i put a default route to site a and asked the router on site B to send all traffic to site A . once the traffic comes to site A it should be ok.

There still remains lot of questions un answered . do you have nat configured but we can get to that after you try this please if possible try to do this after office hours and also post your running configs .

thanks should work i think
