Hi, just a little more information about your setup.
Have you left Wingate's firewall enabled [ENS installed and active] as well as Windows firewall?
You are connecting from the same machine as Wingate and not a client on the lan?
The IP addresses chosen in the Class A subnet, it would be better to have one on another eg: External 10.14.1.xxx // Internal 10.14.0.xxx [or even Class C // 192.168.0.xxx].
Check Adaptor usage in Gatekeeper.
