Hello,
I have successfully set up a site-to-site IPSec Tunnel connection with the following details, using 2 2821 Routers:
Router A
Internal Network: 192.168.1.0/24
Internal Interface: g0/1 192.168.1.1
External Address: 7.7.7.1
External Interface: g0/0
|
Router B
Internal Network: 192.168.2.0/24
Internal Interface: g0/1 192.168.2.1
External Address: 7.7.7.2
External Interface: g0/0
|
A host in Network A can ping/access a host in Network B (including Router B) via the IPSec Tunnel and a host in Network B can ping/access a host in Network A (inlcuding Router A).
The problem is that Router A can't ping Router B or any hosts in Network B and Router B can't ping Router A or any hosts in Network A.
So on Router A, the command: ping 192.168.2.1, times out.
Yet, when I try on Router A the command: ping 192.168.2.1 source g0/1, everything works right.
I suspect that both routers try to access the remote internal networks using their external interfaces instead of using the IPSec Tunnel. How could I fix that?
