Is Double VPN connection with XP client, Win2003 VPN server possible?
Posted on 2006-07-10
We have a commercial program that downloads licenses from a license server. We want to use this program from home by connecting to our company VPN server, but the ip addresses the company hands out don't work because the program only responds to license requests from ip addresses on the same subnet. Unfortunately we aren't able to 'play' with the company VPN server.
However, we have a second VPN server that we do control running on Windows2003. We can't connect to our Win2003 VPN from home unless already connected to the company VPN (due to perimeter firewall). Therefore, I think the remote user will need to make 2 VPN connections, 1 to the company VPN and then 1 more connection to our Win2003 VPN. The second connection depends on the first connection. Is this even possible? Also, how to insure with a Windows XP laptop that it sends all packets out the interface of the second VPN connection? Do you need to do route print on XP to view and modify the routing table?
We tried the double VPN connection but the XP laptop still couldn't get a license. I think the problem is probably that it's sending the license request out the first VPN connection's interface. It also may be that you can't have a double VPN connection when 1 connection depends on the other(not sure if Windows is smart enough to handle this, or if its even possible)
Let me know if you need more info.
Thanks for the help!
