There are usually two common problems associated with VPN connectivity:

You can't not connect to the VPN server at all.
-If you can not connect to your VPN server at all and have a router (Westell or other) the VPN application may require you to either open certain ports, assign an IP to a specific computer, or use a separate PPPoE client directly on the computer. For more information please click here.

You can connect and authenticate to the VPN server but nothing else happens and applications stall, time out, or fail to load.
-If you can connect and authenticate but applications stall, time out, or fail to load your MTU (Maximum Transfer Unit) may be incorrect. The following FAQ section is designed to help you find the proper MTU size for your VPN. To determine the correct MTU size for your VPN please click here.

Helpful hint: One way to verify whether if it is an MTU problem is to try and access the application or website via dial up access. Since dial up uses a default MTU of 576 bytes you will not have the same problems as broadband. If you have problems with both broadband and dial up access then the problem is probably something else.
