Is this possible ( and simple) ??
Problem
- Have client with uVNC_SC behind NAT router.
- Viewer on laptop is also behind a NAT router ( eg. in hotel room) and it is not possible to change router port redirection.
Solution ?
On my office PC : run a VNC port relay program that will transfer all data between ports 5500 and 5900 ( VNC serve and Viewer ports) ?
The RelayVNC.exe program would look like a viewer to the uVNC_SC program and look like a Server to the VNCViewer.
Sounds simple, is it??

Re: Getting uVNC SC to work with Viewer when both behind NAT
From what I understand pchelpware is entirely new program code, currently in beta etc...
What I was thinking was a "simple" application that would allow existing tried and tested SC & uVNC to do what pchelpware is doing.
Also because the relay application is emulating a 'viewer' to a vnc server and a 'server' to a vnc viewer it may be possible to use it with other vnc variants too.

Re: Getting uVNC SC to work with Viewer when both behind NAT
Thanks, you are right it seems repeater in mode II is exactly what I was talking about. I'll check it out and pchelpware too
It is amazing what you can learn if you understand what you read.
