I have now finnaly set up my firewall but i can't send files with msn messenger so I was wondering does anyone know wich port the messenger uses for file sendings? And how I'm supposed to set this up? It may or may not be relevant that I'm runnig Osx. I've tried an google seaerch but probably had the wrong search opptions or something because i didn't come upp with any information I hope this is in the right forum.

Thanks beforehand
