routing

Unanswered Question

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

This might be an issue with RRAS.check the vpn configuration on both the ends between the site for any configuration issues as you are able to ping from internal office to the remote site.Also try using the latest microsoft patch which might solve the issue.
