I have a small hurdle to get over, hopefully one of you can assist.

brief overview:

2 sites; 1 main office 1 remote site

main office:

cisco 1801 adsl POTS

Windows 2003 sbs

internal - 192.168.1.x

external interface - 192.168.3.x

remote branch:

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:

192.168.3.2/24

gw 192.168.3.1

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.

cheers
