I am connecting via VPN to my university. It worked flawlessly until a few days ago. Then, when I connected via the VPN client, although it seems to logon fine, I suddenly lose all connection, and I do mean - ALL - connection; I have no ping to the machines in the university (for which I am opening the VPN in the first place), nor to my own router, even. The problem disappeared a day later, but now has returned. My ISP says they don't see any problem on their side. Using windows 7 with cisco vpn client. Can anyone give me advice as to how to troubleshoot this?
