I have a VPN set up through Cisco AnyConnect 3.1.04072 on a Windows 8 laptop. I can connect to the vpn, but as soon as I do, all internet traffic stops. I've been researching for days now and I haven't found a solution. A few suggestions I found included unchecking "Use default gateway on remote network" in properties, updating drivers, and editing a key in regedit.

We have three machines that use AnyConnect (a Mac, a Win7, and my Win8) with the same vpn service and mine is the only one with this problem. Also, it began only a few days ago when Cisco released the 3.1.04072 update.

Here's the configuration...

Pinging the DNS server 172.16.1.200 is unsuccessful. I've tried changing the DNS server in the control panel properties to other things like google's DNS, but the result is the same. All pings fail, as does tracert and nslookup:

>nslookup    
DNS request timed out.
timeout was 2 seconds.
Default Server:  UnKnown
Address:  172.16.1.200

If someone could point me in the right direction I would really appreciate it!

Have you tried to roll back the version of the client? –  Ramhound Dec 17 '13 at 14:09
    
Yes, it doesn't work because the client updates itself when it connects. –  Evelyn Dec 18 '13 at 1:12
    
Did u check the ad account is in the security group allowed to connect to the VPN server? Simple test will be to use the ad account on another machine (where the vpn client works) or use another ad account thats is connecting fine with cisco vpn client on another machine. –  user299217 Feb 11 '14 at 13:11
    
Did you found the solution for you problem? I have the same on Win 8.1 x64 –  Marek Dec 11 '14 at 13:24
    
Please comment on the points in the article AnyConnect Support for Windows 8.x. Have you tried AnyConnect 3.1.06073? –  harrymc Dec 11 '14 at 13:39
