Open port to connect

Hi, I just installed the new version with Screenshare and had trouble connecting.
The solution was to manually open the port 5901 over the protocol UDP (having peeked in your code ;) ).
I am working on an OpenSuse linux distro.
Now it works, thank you so much!
(by the way, that is also the trick to use Screenshare with the official app on linux, using wine)
