Your virtual switch configuration is different somewhat, as well as the hypervisor. We're running vSphere on this side of the equation and using standard vSwitches with a VLAN based port group for the VM network. That doesn't matter in this case because there isn't an issue with virtual switch configurations. > OK.... I have installed Windows 2008 Server in a VM.

You confirmed that you can connect at least briefly to a Windows Server VM from inside a network, with no vpn in the picture. Based on what I've found, I am now 100% certain there is an issue with gnome-rdp / Reminna AND with Network Manager. We also need to get off of the host name resolution thing. This is not where the problems we're having are coming from. "It works on my system" is never confirmation. It isn't working on multiple F16 and F17 systems, and it IS working on multiple Windows 7 systems when using the Cisco VPN client. Case in point: I am certain there is an issue with Network Manager and vpnc. Why? Because on multiple systems, with both F16 and F17, I am able to show the following: Connection using Network Manager / vpnc first connects, then hangs. Specifically, I did: 1) Start vpnc based connection on Network Manager 2) Attempted to connect via ssh to a Linux based VM on the inside network: (command was "ssh -X -l cwilliams jericho.risingstar.local") 3) ssh connects successfully, but then eventually hangs after a few seconds. There is nothing in the ssh log or Network Manager log that I'm able to find regarding any kind of error. The ssh session just stops working. Further, all other vpn connectivity stops working. The contents of /etc/resolv.conf are irrelevant because the host name WAS indeed resolved. It does correctly show the proper domain search and DNS information though. But as I just mentioned, this is irrelevant to the problems we're seeing. The VPN connection simply failed, and with no errors. When on the inside network: 1) Connect using WiFi connection on an F17 laptop, receive address via dhcp 2) Connect via ssh to the same machine with the exact same command as above. The ssh connection remains up and stable. Again, the contents of /etc/resolv.conf (and nsswitch.con for that matter) are irrelevant because host names are being properly resolved. HOWEVER: Connect via Reminna or gnome-rdp to the internal system. the rdp connection first starts, then eventually hangs after about 5 minutes. Again, host name resolution is NOT the issue. When connecting from a Windows 7 system using the Cisco VPN client, the VPN connection remains stable AND Remote Desktop Connection for Windows works as expected. This is doing this with a VM on the same Linux system that fails when using Network Manager / vpnc. Since the VM is using Network Manager without vpnc under the covers (VMware Workstation using a NAT mode virtual switch that then talks to Network Manager - as an aside, when doing client based VMs, bridged adapters should be used only as a last resort because you chew up IP addresses needlessly), this leads me to believe there most likely is an issue with vpnc itself. I actually have held off on what I really know on networking here - I know for a fact that the network configuration is correct. I also went through our ASA box again and re-validated the configuration is correct. I'm not going to display the entire network configuration here (security). That said, we need to stop troubleshooting this as a DNS or host name resolution issue. It is not. There is, however, an issue with vpnc on Network Manager not working correctly. There also is an issue with rdp sessions (I noticed that Reminna and gnome-rdp both appear to use some of the same rdp libraries, so this isn't a surprise). They drop after anywhere from a few seconds to a few minutes of activity when connected to a Windows Server 2008 system, and they do this regardless of if Network Manager or vpnc are in the picture. I guess I'll just file a Bugzilla report on this and then take things from there. Thanks for trying...
