I run a standalone 2008 r2 server that acts as a dial in VPN server. The clients dialing in needs to communicate with eachother and do not need to access either the server itself or lan/wan. To do this I want each client to have a static IP.
In user settings I've set a static IP for each VPN-user and normally that works fine. But when the connection is lost (bad connection over 2G/3G) and reconnected the user gets another IP. Sometimes the new IP actually is set as static for another, not currently logged in, user account.
How can I prevent the server from assigning anything other than the correct IP?
thanks!
