Every year we hold a music concert in a hotel ballroom.

My setup is the camera input going into a transcoding computer that is then relayed to my streaming server off location, which is then served to the clients.

Everything works well when I tried the setup from home, but at the event the hotel's internet connection was blocking every port I tried on my local transcoding computer.

Is there any ports that "usually" is open and available? The hotel staff know nothing and couldn't help.

Well, if you have the permission of the hotel staff, there's various ways to determine what ports are free - nmap for example or grc's shieldsup web service.

If there's absolutely no free ports whatsoever, i might ponder testing hamachi since in addition to being a VPN software, it uses various techiques to work inside a firewall

The best bet is 80, then try 8080

I did try 8080, and I was under the impression that http being on 80 would block it from other programs using it? Thanks for the quick answer. –  Mitch Apr 24 '11 at 0:45
    
also try port 443. you can have more than one port on a connection - else web servers wouldn't work. –  Journeyman Geek Apr 24 '11 at 3:26
