MSN Messenger

By ogie_2001 ·
I have 4 machines on my home peer-to-peer network with 1 machine acting as a file server used only for backup purposes. All machines are presently using 98SE. These machines are connected to a 3com 3C510 gateway, which has a firewall, and is connected to my high-speed dsl modem. I am also using Zone Alarm Pro on each machine.

I have been unable to send files and photos to other people I connect to with MSN Messenger since setting this up, or even other machines on my network. I can still receive files that people send from outside my network but every time I try to send something it is blocked. I have shutdown Zone Alarm on 2 machines and tried to send a file and gotten the same results.

Since the problem doesn?t seem to be relatedto Zone Alarm it must be that a port has to be opened in the gateway but I?m not sure which one and if any other changes have to be made. The options I have are:

Client Privileges:

Allow or block
(Presets listed - all supposed to be enabled)
E-mail (110,25), Internet (80), FTP (21), News (119)


Special Access:

ID, Trigger, Incoming Ports, Enable
(Presets listed but not active)
AUTH (113), DNS (53), FTP (21), ISAKMP (500), POP3 (110), PPTP (1723), SMTP (25), TELNET (23), and WEB (80).


And


Virtual Server

ID, Service Port, Server IP, Enable,
(Presets listed ? Ports 20 and 21 active for 1 machine)
AUTH (113), DNS (53), FTP (21), ISAKMP (500), POP3 (110), PPTP (1723), SMTP (25), TELNET (23), and WEB (80).

Can anyone explain what ports to unblock and any other changes that need to be made?

Thanks in advance.
Dan

Look here:

It's a known issue. Another quote:

For more information about which ports a network administrator should open for MSN Messenger to work, please see the "Guide for Network Administrators" in Help.

For instant messaging

To allow your network users to have a direct connection to instant messaging services, you will need to:

Open outgoing TCP connections to Port 1863 on your proxy servers.
Let your network users know which kind of proxy server your network uses (HTTP, SOCKS4, or SOCKS5) and provide them with the corresponding details (server name, port number, and so forth) so they can enter that information on the Connection tab of the Options dialog box (Tools, Options).
Make sure the internal local area network has access to the Domain Name System (DNS) servers to resolve the names of external hosts such as messenger.msn.com.

For file transfer

Both incoming and outgoing TCP connections use this range of ports: 68** to 6900. This allows up to 10 simultaneous file transfers per sender. If you open only Port 68**, users will be able to do only one file transfer at a time.

The TCP ports need to be configured so that sockets on a port remain open for extended periods of time.
