Configure SSH tunnel to reduce lantecy for gaming

I have a basic SSH tunnel setup through CentOS 6 on a VPS. I wish to use this as a gaming tunnel, meaning by playing games through this SSH tunnel it will reduce latency (as the VPS is located near the gaming server). Users have their own resitrcted username and password for connecting to the tunnel itself. Here is an example of what would be setup on a user trying to connect would follow: [login to view URL] My problem is that once you reach the 'Freecap' configuration, it gets an authentication error. Connecting to the SSH tunnel itself is working fine.
