Does anyone know of a reason why I cannot connect to my office over VPN using DSL from Verizon? I have actually connected once or twice, then try to go back in and the connection attempt just hangs. It is a PPTP connection. Other coworkers have cable and it works fine and I am set up the same way so I question whether Verizon blocks the traffic. I run Windows XP SP2. Any help would be appreciated.
