I have successfully set up a VPN between two WRT54GL according to this guide.


-> My problem is that the Server LAN can not ping/connect to anything on the Client LAN, except the Client WRT54GL itself. (The Client WRT54GL can ping any random node on the Server LAN)


The Server side WRT54GL is connected to Internet, while the Client side WRT54GL is behind a router/NAT/DHCP-server (Thomson TG784 with a very limited firmware). The Client is set to "Operating Mode = Router"

I believe that my problem is related to the fact that the Client is behind the TG784. But I am not able to figure out any successful routing...

I have looked through the following post but I have not been able to an analogous implementation.

I would appreciate any hints/solutions, that can help me fault tracing my setup. Thank you!
