Hi Jurgen,
You say you set the ip- forwarder option on in the registry? This shouldnt be required as wingate has a option within it that does the same thing.
Extended neworking driver >> general tab >> support for multiple subnetworks(router)
I can make a stable vpn connection but i only can connect the client pc from the server or the server from the client PC.
It is not possible to see the Lan behind the server or the client pc.
does the client have a valid cert? Also you mention that firewall is off is this off on both the client and the server?
