Hi Ekkas2,
"How can I redirect another port number, say incoming 2559 to (Lan) 10.0.0.2:5900"
1. Internet Hardware router forwards TCP Port 2559 to the external side of WinGate.
2. In WinGate setup a port redirection as shown in this image.
Please take note of the "Don't Translate Source IP" option, and the "Override Port" option.
3. a) For the computer on 10.0.0.2, it needs to know how to return the packets to the remote VNC Client. This can be done with a default gateway (NAT, to test, on the 10.0.0.2 computer, ping
www.wingate.com), or with the WinGate Internet Client (WGIC)
3. b) If the packets are coming in through WinGate, it should also be returned through WinGate too; i.e. if 10.0.0.2 has it default gateway pointing somewhere else, you are potentially going to have problems.
