How do I join a game?

its been 8-9 yrs since i've played bolo in hs on macs. now im trying to play on a pc with winbolo. on my startup screen i have the option of TCP/IP, Local Network, and Internet. I dont care which i select, i just want to get into a game. When i click Refresh.. its says error connecting to tracker. What do I use for my tracker address and traker port? Then there is an option to join by address. if i see a game being played on winbolo.net and i see this IP Address
ool-435278d5.dyn.optonline.net:62767
what do i enter, and where? It automatically says 27500 for my UDP port. IF this is wrong, how do i find my UDP port? thanks

ok, first the tracker address is tracker.winbolo.com port 50000
second if you find a game on .net you just click "join" and it will automatically load winbolo to the correct screen, set your own udp port to zero for it to randomly pick one for you. but it doesn't actually matter what your own udp port is unless your running a firewall or something and need to get out on a certain port.
