VPN same IP address problem
Hello! I've noticed a problem with my SSTP VPN connection on Windows 7 towards Server 2008R2 (but I guess it's a Windows VPN problem in general). My home router gives me IP address 192.168.1.10-192.168.1.20. Now, my work server is configured to give an IP from 192.168.1.10-192.168.1.20(or 30). Should my internal (home IP address) be the same as my work (VPN IP address), I don't have any connectivity towards my workplace. I could either change my router, or use 192.168.5.* range on the VPN server, but that is just half the solution. My coworkers connect to our server from all over the world, and there is no way to guarantee that their current network won't use the same IP as they get from our VPN. I know it's unlikely, but possible. And I really don't think that VPN should work 99% of the time. Any help would be appreciated. Thank you for your time.

The vpn ip range should not belong to any ip range in the internal network, this as general rule. Client connecting through vpn should be routed in order to reach the internal network. This likely will not happen for mobile vpn connections, since users connect with public ip. In a branch office schenario, that restriction needs to be taken into the account of course and plan the ip ranges accordinglyVincenzo MCTS, MCTIP Server 2008 | MCTS Exchange 2010 | WatchGuard Firewall Security Professional

WWAN provider in our country uses private network IP range. Wifi in every hotel uses private network IP range. Cheap ISPs use private networks. Universities, ... and the list can go on and on :( So you're saying that there is not a solution for this?
