Windows Messenger Ports/Router Config



Does anyone know what ports are used by Windows Messenger for PC to PC voice conversations? I need to know which ports to have forwarded to my main PC. I'm actually, not sure exacly how messenger gets text chat too all of the machines on the router either, but somehow it does..... I will be happy if just the main PC can have voice forwarded to it. Any info would be appreciated.

Thank you,

Set your router to forward the following ports:

Voice: 6901

File Transfer: 6891-6900

Hey EP! All good with me, applying for Microsoft MVP right now, should have done this a while ago.

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
