Forcing programs through a VPN?

[fddrummer06]

On my school's wireless network, you must connect to a vpn to access the internet. I have my 6700 configured for this and I can use PIE with no problem. how can I force applications such as AIM and my pop3 email to connect through the vpn so I can use them on my school's network. I've tried everything I can think of with no success. Any help would be greatly appreciated.

EDIT: Update on the status, I can connect with AIM if i connect to the VPN then try to sign on, but the VPN connection does not stay active and disconnects after about 5 minutes. I still cannot use Outlook with Wifi through the VPN. Is there any way to keep the VPN active until I disconnect it?
