Hi, I've been wrestling with this for a week now to no avail... what I have is: - 2 LANS with an XP home client on each (Windows firewall disabled). - 2 WRV54G wireless gateways (both with latest firmware). - 2 DLink DSL 300T broadband routers connected to the WRV54G's (both with latest firmware). - A static IP address on both sides. I have followed the official guide for setting up the VPN tunnel and that has worked fine - both wireless gateways report the VPN status as 'Connected'. However I cannot ping from the XP machine on one LAN to the other in either direction. Nor can I map the shared network drives on any of the machines in either direction. I have also tried using the Quick VPN client to connect and whilst the initial connection is successful I get a message box some minutes later stating that the "remote gateway is not responding". I have also tried (and failed) doing things the XP way by: - Enabling remote desktop connections on 2 test PC's (one either side). - Setting up an XP Advanced Network connection to accept incoming connections. - Creating a new XP VPN connection. None of this has worked. Can someone shed some light? Is it because the DSL 300T's are not allowing network packets back in? Please excuse me if this is all a little newbie. Many thanks, Rob.
