im trying to setup remote vpn to a 2012 server inside my UTM9 firewall by just setting up two DNAT's one for PPTP and one for GRE to the 2012 server, I can get partially working because it connects but then hangs at verifying user credentials and doesn't go any further. If I test the client by trying to connect to the local IP of the 2012 server it works fine so this tells me that the firewall is not passing all the information. Is there something special i need to do to get this configuration to work? any help would be appreciated.
