Windows 7 AnyConnect Client to UC540 No DNS

I'm attaching an AnyConnect Client, latest version 2.5.3046, to a UC540 with a Windows 7 64 bit PC.  Connects fine and I have access to the private network.  However, the DNS Servers entries for the tunnel adapter on the PC have IPv6 addresses in them.  As a result I cannot do any name resolution while connected.  The UC540 is set for full tunnel mode.  This is what else I've tested:  Same client on an XP attaching to same UC540 works fine; older AnyConnect client, 2.5.2014, on the same Windows 7 machine has same results.

Hi John,

Can you paste the output to 'ipconfig /all' from the Windows 7 PC that shows the DNS Servers have IPv6 addresses?  Are you pushing DNS Server addresses in the webvpn config on the UC540?  Can you also paste the output to 'show run | se webvpn'? (you can X out the ip address part)

Thanks,

Brandon
