-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft MechWarrior 4: Vengeance 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you attempt to connect to a multiplayer game of Microsoft MechWarrior 4,
you may receive an error message that states "Unable to Connect" or "Server
Connection Failed."

CAUSE
=====

This behavior can occur when you connect to the MechWarrior 4 server through a
proxy server or firewall.

RESOLUTION
==========

Firewall users must open up ports to use ZoneMatch and DirectX 8 DirectPlay port
ranges to successfully participate in games. Matchmaking needs the following TCP
ports opened:

  
  27999
  28805
  28806
  28807
  28808

  For PINGs to work properly, UDP port 28800 must be open.

NOTE: To have statistics posted to stats.zone.com from behind a firewall, you
must have TCP port 9999 open for outgoing connections.

MORE INFORMATION
================

In addition to the ports listed earlier in this article, the DirectX8 DirectPlay
ports are outlined in the following article:
