Is this enough info to get it up and running on the WNR3500L?
No VPN connection can be established with native firmware.
Either you configure the VPN on your computer, or you must use an alternative firmware.
If it is a PPTP connection the best choice is dd-wrt (no encryption in TOmato PPTP), and perhaps TomatoUSB-vpn for openVPN.
