I have an adtran 4205 and a cisco 1800 at two offices. I have 2 t1's at each site installed for load balancing, etc dedicated to network traffic only. I used multilink ppp and have the ppp1 interface on each router up, and both t1's on each router showing up. all is fine. for the ppp 1 interfaces on each router, I used 192.168.1 255.255.255.252 and 192.168.1.2 255.255.255.252 respectively. All seems fine there. I can ping and telnet back and forth using those addresses. For the main office router, the important lan range is 10.1.3.x and 10.1.5.x 255.255.0.0 and at the remote site 10.2.4.1 255.255.255.0 Both sides have a seperate firewall which holds the routes for internet traffic on a seperate connection. The main router has 0.0.0.0 0.0.0.0 10.1.3.20 (firwall at main site) and the remove site has 0.0.0.0 0.0.0.0 10.2.4.10 (firewall for remote site)
From REMOTE Test Router: (10.2.4.1 255.255.255.0, 192.168.1.2 255.255.255.252)
ping 10.1.3.5 source 10.2.4.1 request timed out
ping 10.1.3.5 source 192.168.1.2 success!
ping 192.168.1.1 source 10.2.4.1 request timed out
From MAIN Test Router (10.1.3.5 255.255.0.0, 192.168.1.1 255.255.255.252)
ping 10.2.4.1 source 10.1.3.5 expired TTL in transit
ping 10.2.4.1 source 192.168.1.1 request timed out
ping 192.168.1.2 source 10.1.3.5 success!
Is this a static route issue? I even tried configuring the 0.0.0.0 routes as the 192.168.1.x addresses of the other routers, or even 0.0.0.0 0.0.0.0 ppp1 and still cant talk accross to the other LAN. Any suggestions?
