We are using a CISCO ASA 5520 ASA Version 8.3(2). We have a couple of users that use AnyConnect version 3.1. When they VPN in they are unable to get to some websites. They just do not load. Other users have tried to use their credentials on their PCs with the same results. When we VPN in on other PCs with versions 2.4 to 3.1 we have no problem getting to the websites they are having trouble with. Some websites are facebook and amazon. When users VPN in they are all under the same group, they get their IPs from the same pool and follow the same policy. Any ideas?
We found a fix for our problem. Websites were failing to load while connected to the VPN. Resetting TCP/IP fixed this issue. Users are able to navigate to websites after running the netsh int ip reset c:\resetlog.txt in the command line and then reconnecting to the VPN. The issue was only affecting a couple of PCs.
