tcp 5900 & 5988
udp 5900 & 3283
and you would need whatever port iChat uses open also...PowerBook G4 17”, Mac OS X (10.4.10)

Did you have any success? I have been having the same problem you described.Macbook Pro 15" Santa Rosa 2.4Ghz, Mac OS X (10.5), 250GB harddrive upgrade
Currently Being ModeratedNov 22, 2007 8:55 AM (in response to Wildatheart)Yes, for the moment only bad news.
With our engineer, we checked screen sharing from inside the firewall and from outside. It looks like when you do screen sharing, a random port is selected for communication -- not the tcp and udp ports used by Apple Remote Desktop. In our tests, they were ports on the order of 50 or 60 thousand something, varying each connection.
THis means that you can't just open 2-3 dedicated ports, that is of no use (at least, we didn't find how to do it). This in turn means that very few institutions will accept to let you use screen sharing, because they should open big ranges of ports.
If anybody else has some suggested solution, we can try it out.
