Har du en fast ip adr. og ligger du bag en firewall som din netudbyder har
installeret,
så kan du ikke bruge tale eller vidio. har selv haft problemet,
jeg måtte have en ny ip adr. for at kunne bruge msn. til tale.

MSN Messenger Service Can't Do File Transfers/Voice Connections [Q278887]

PSS ID Number: Q278887
Article last modified on 11-18-2000

======================================================================
----------------------------------------------------------------------------

The information in this article applies to:

- Microsoft Windows versions 2000, 2000 SP1 Advanced Server
- Microsoft Windows versions 2000, 2000 SP1 Server
- Microsoft Windows 2000 Professional
----------------------------------------------------------------------------

SYMPTOMS
========

After you configure Windows 2000 Server to serve as a Network Address
Translation (NAT) router, client computers that use the NAT router are not
able
to use MSN, The Microsoft Network Messenger Service version 3.0 program to
transfer files or establish voice connections. This problem also occurs when
you
are using Windows 2000 Professional with Internet Connection Sharing (ICS).

CAUSE
=====

This problem occurs because MSN Messenger file transfer and voice features
do
not work through NAT routers because there is no NAT editor to correctly
translate the IP header information.

RESOLUTION
==========

To work around this problem, install Proxy server, create a Winsock protocol
definition for TCP ports, and then install the Winsock proxy client on the
computers that use the proxy server.

Winsock Protocol Definitions
----------------------------

To enable voice communications, make sure that outgoing TCP connections from
port
6901 are enabled. Also enable UDP packets where either the source or the
destination port is 6901.

To enable file transfers, enable both incoming and outgoing TCP connections
to
the 6891-6900 range of TCP ports. This allows each sender to perform up to
10
simultaneous file transfers. Note that if only TCP port 6891 is open, users
are
only able to perform one file transfer at a time.

To enable messaging, enable outgoing TCP connections to TCP port 1863.

NOTE: In MSN Messenger, do not click to select the "I use a Proxy Server"
check
box on the Connections tab of the MSN Messenger client.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products that
are
listed at the beginning of this article.

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

By default, a NAT router translates IP addresses and TCP/UDP ports. If the
IP
address and port information is only in the IP and TCP/UDP headers, then the
application protocol can be translated properly.

Some programs and protocols (such as FTP) store IP address or TCP/UDP port
information within their own headers. For these protocols or programs to be
able
to work through a NAT router, there has to be a method of opening the packet
to
translate the address or port information that is contained in the payload.
To
accomplish this requires a NAT editor.

Windows 2000 Server has NAT editors for the following protocols:

- FTP
- ICMP
- PPTP

Windows 2000 Server does not include NAT editors for the following
protocols:

- SNMP
- LDAP
- IPSec
- Microsoft COM
- RPC
- H.323
