Firewall and MinimWatch

[DrD]

With its firewall active, the machine running MinimWatch is unable to establish a connection with MinimServer (the menubar icon remains greyed-out).

Allowing access from TCP ports 49000:49999 and to UDP ports 49000:65535 "solves" the problem. MinimWatch is then able to establish a connection. But a more fine-grained solution would be desirable.

What ports need to be open for MinimWatch to function?
