Changing the messenger port?

[boe]

Is it possible to change the port for Windows or MSN messenger? If so will
it be able to connect with clients using the standard messenger port?

Greetings Boe,

I'm not sure which function you're referring to, but no, Messenger's ports are set -- here's
a
quick list:

Basic text messaging/connection to Messenger server: port 1863 or 80 TCP and 443 TCP
File Transfer*: 6891-6900 TCP (this port range is not valid for MSN Messenger 6 clients
sending/receiving to other MSN Messenger 6 clients)
Webcam**/*: 9000-9999 or 80 TCP
Audio*: 5004-65535 UDP
Video Conference (XP only)/Start Camera*: 5004-65535 UDP
Remote Assistance (XP only)*: 3389 TCP
Whiteboard/Application Sharing (XP only)*: 1503 TCP
Launch Site Games**: 80 TCP
* denotes features which can use Universal Plug and Play (UPnP), UPnP file transfer only
available in Windows Messenger 5, MSN Messenger 5 and MSN Messenger 6
** MSN Messenger 6 feature exclusively

Hi Jonathan,

in earlier threads I read that the Logitech "Webcam" feature of MSN 6 does
*not* need UPnP. Is it optional? Thanks for clarification.

Hi Thomas,

That's correct, the "Webcam" functionality can use a relay server to basically "relay" the
webcam, so a direct connection isn't required and therefore UPnP isn't needed for NATs (but
recommended).
