I am trying to get this client to work through my 1720 router at home. I have the client set up and it works fine via a dial up or with my usb modem. Whenever I try to connect via my 1720 the VPN client fails to connect. I have no access lists on my router although it is performing nat on the LAN side. A look at what is going on with ethereal shows the following .. "ARP who has 10.0.255.10" and shows no sign of the VPN client looking for my gateway (10.0.0.254/24) My client address is 10.0.0.11/24 My router ethernet is 10.0.0.254/24 I have no 10.0.255.10 on my network Any help appreciated ! Drop the ZZZ to reply Cheers ...
