[VPN] Unable to see windows domain information (WINS) using VPN

[James Archbold <[EMAIL PROTECTED]>]

I cannot get any WINS resolution through my Cisco VPN 3000 Concentrator.

I connect to my ISP then to the VPN 3000. I can successfully establish a
tunnel and can resolve names using DNS but I cannot resolve any NetBIOS
names from my WINS servers.

The VPN box is connected to the DMZ of a PIX firewall.

I can ping the WINS servers and all IP routing is working.

I am using the Cisco VPN Client 3.6.3a.

Below is a ipconfig /all before and after the VPN connection is
established.  My IP address through the VPN is allocated from an IP pool
on a RADIUS server and my WINS configuration is also set-up from the
RADIUS server. (RADIUS server is Cisco ACS 3.1)
