Title says it all, is it possible to use Team Viewer in an environment where port 5938 is being blocked? Is there some kind of setting that can be used to establish connections over a different port, or is this a hard requirement?
21 Answer
If TeamViewer can’t connect over TCP port 5938, it will next try to connect over TCP port 443, and finally it will try on TCP port 80.
However, if running on Android or Windows Mobile, it can can only connect over port 5938.
If all these ports are blocked, then you are in trouble.
