i think u have to check the firewall settings may be u have dropped some ports…

You must check your firewall configuration. All the ports used by msn must be opened.
This is the list of the ports used by msn:
-80 (tcp) : Conversation, games
-1863 (tcp): Conversation

  • 6891-6900 (tcp): files transfers
  • 6901 (tcp and udp) voice conversation
  • 443 (tcp): login, password, secure connexions
  • 9000-9999 (random ports) (tcp): WebCam
  • 3389 (tcp): remote assistance.
  • 1503 (cp) : white bord, shared applications

Good Chat

all those ports are open, it happends that in some computers msn is working and in others not… i did reinstall msn on the ones not working but is the same …
could it be the ethernet adapter of the ones not working the problem??? coulkd it be possible even though the pc is surfing?

Did u disable masquerade or src-nat?
If u disable masquerade or src-nat any massanger wont work :slight_smile:

both are working(enabled)

If you are making connection to your ISP with PPPoe check that your MTU setting is at 1492, that solved the problem for me

it using static ips,no ppoe..
what ive found out something is eating up my upload speed..

i have 3meg down and up but ive noticed it will only displays as 250 o300kbps of upload while 3000kbps download.

You may use torch to track down the addresses and traffic that uses your upload, make sure that these ports are opened and you are using 2.9.46 version.

reboot your router
