Doesn't work over the internet :-(

[Hervé]

Hi!
I'm a french user of the desktop rover and his telecommander.
I put a spycam on the rover and i send video stream on a webpage.
Now, i'm trying to receive control commands from a friend (who's got the software) over the internet...but it doesn't work :-(

He's in remote mode, me in server mode, he has my IP.
We're are all behind a proxy router. Which port should we use ?

I don't receive anything from him :-(

Anyone succeded in the use of telecommander over internet ?

Thanks for your help
