I have a Windows 7 Enterprise vm running Cisco VPN Client 5.0.07.0290. I'm connected to this Windows box via RDP. I have a Linux server that needs to route through the VPN on this Windows server. Attempts to use vpnc to connect to the VPN server on the Linux box have resulted in "vpnc: no response from target". The Linux box can reach the VPN server via nmap on ports 500 and 4500, so we know the issue is not with the network but vpnc. The windows vm is in the same subnet as the Linux box. I can reach the windows box via the linux server and my workstation.
However, when I start the VPN connection, RDP gets disconnected. Windows firewall is completely disabled, transparent tunneling is enabled in the VPN client (IPSec over UDP) and "Allow Local LAN Access" is enabled. When I load the virtualization console for the Windows vm, I can confirm that it now has access to the VPN.
What appears to be happening is that the Cisco VPN client is not honoring the "Allow Local LAN Access" setting, as far as I can tell.
Is this a known bug perhaps? Anyone have experiencing routing through a windows machine in order to use the Cisco VPN client?
