John,
I've tried without tunneling: it is working! But in my case there is a firewall between client and server. Does somebody know which ports are used? What I found out so far is that the client is listening on port 4713tcp. So my ruleset right now has ssh in one direction and 4713 in the other. Will the ports change if you have more then one client or with a new connection? Can it be configured somewhere?
Regards Frank
Now I have the next problem. I tested with watching videos on youtube. At first everything works fine but after approx. five minutes sound stops working. If you select another video flash seems to wait for something. If you try to exit/close firefox you have to wait some seconds. Do you have any suggestions what may cause this? With a local login everything works for at last ten minutes so I assume it is no problem with the server.
Have you tried UNchecking "use SSD port forwarding to tunnel sound system connections through firewalls"?
I've found that sound tunneling is broken on all windows x2goclients after 3.01-13. If I disable the sound tunneling on the later clients, then videos and sound play fine. If I enable it, the videos and sound do not play (they just freeze). Of course, my x2go connection is not going through a firewall.
