I have a small hurdle to get over, hopefully one of you can assist.
2 sites; 1 main office 1 remote site
cisco 1801 adsl POTS
Windows 2003 sbs
internal - 192.168.1.x
external interface - 192.168.3.x
cisco 857 adsl POTS
internal - 192.168.0.x
There is a site to site vpn configured between the two sites. The tunnel is stood up, and I am able to ping from the internal network at the main office 192.168.1.x to the remote site 192.168.0.x
The problem comes in when I try to reverse that procedure; I am unable to ping from the remote site 192.168.0.x to the internal lan at the main office 192.168.1.x
I can ping from the remote site 192.168.0.x to the external network at the main office 192.168.3.x
RRAS is configured on the win2k3 sbs server, and I think this is where the problem is coming in.
the external network at the main office is configure as such:
192.168.3.1 is currently the old internet connection, my shiny new cisco 1801 is configured with 192.168.3.254
What do I need to implement/do to enable traffic to pass from 192.168.3.x to 192.168.1.x
I have tried to ping from the 1801's console to the 192.168.1.x network without any luck, so its not a problem with the vpn tunnel.
It must be something to do with RRAS.
