UltraVNC

hi, i don't know if this feature is available, let say the client downloaded the software, i'm remoting the client's screen, i like to show my own screen to my client instead seeing client screen, is this possible once i finished doing what ever on the client machine, then click button to show my ...

it is possible make support.exe check if gatway allow using upnp to open router port 5500 ? so there is no need to do port forwarding ? if that feature available, it will be awsome... i love this tool...

thanks
