I am currently attending a university which allows internet access by opening PuTTY and keeping it open while I surf. If I close PuTTY I no longer have connection to the internet. I am trying to use a VPN and PuTTY at the same time but PuTTY always experiences an error when I open the VPN connection. The issue is not throughput overload. I am running Windows 7 Ultimate x64. If anyone has any experience with this "tunnel within a tunnel" configuration your help would be very appreciated. Thanks!
