MSN Messenger 6.1 ports.

[Bjarki]

Hi there.

In my company we are using MSN Messenger 6.1. I only
would like to allow Chat, port 1863, and close for
everything else, eg. file sharing, Remote assistance,
Whiteboard, Audio/Video.

What i know is chat is port 1863, what about other ports?

I know there is some diffrence btw. MSN Messenger and
Windows Messenger and the ports they are using.

Can someone help give me informations about this.

Regards.
Bjarki

Greetings Bjarki,

If you just allow port 1863 (and 443 for HTTPS authentication), Windows Messenger/MSN
Messenger voice, remote assistance, whiteboard and application sharing will no longer work.
Windows Messenger file transfer (sending) and video conversations will not work, but MSN
Messenger file transfer can actually use the 1863 server connection (the same that the normal
chat is using) to send files. As such, you won't be able to block users sending files
through MSN Messenger 6.x.

Here's a full list of Messenger ports for reference:

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
