Is your VPN gateway behind a NAT or PAT gateway? Then you don't need IP/50. And with PAT it typically can't be forwarded as there are no ports to translate.

Then you probably have to configure a 1:1 NAT with a free IP and forward all traffic.

Where does this /16 come from? If you have one VPN gateway you need one IP address.
