I have this network set up:
site 1(188.8.131.52/24)---Cisco 2600----T1 circuit-----Cisco 2600-------site 2(192.168.0.0/24)
I can ping from site 1, out the DSL circuit or anywhere on the Site 2 network with no problem. From Site 2, I can ping the Internet for somewhere between 40 and 70 pings before it begins to time out. If I then ping the firewall internal port once, I can ping the Internet 40 to 70 times again. If I connect directly to the firewall I can ping the Internet cintinuously with no problems. I'm stumped. Anyone have any ideas?
