Dear benkol,

Sorry.. We are not supposed to answer this question cos you would be circumventing or bypassing the rules of your company or school and it is completely against EE rules

I live in a kibbutz in Israel (no school or company), the network administrator is my friend and he told me to ask you. I am not bypassing anything, I just want to know if there is a way to config MSN Messenger or install a software so it will solve my problem.
Why dont you ask the network administrator to remove the block (in firewall) so that you can do voice

Managing Security Policy in a Changing Environment

The enterprise network environment is evolving rapidly as companies extend their physical data centers to embrace cloud computing and software-defined networking. This new reality means that the challenge of managing the security policy is much more dynamic and complex.

You could try to use another software which supports sound and/or video. It could be MS netmeeting, or Skype (only sound).

First of all, I want to thank you all.
Sunray: My network administrator wont open the ports for voice cause the port range is too large.
dschwartzer: I can't ask all my friends to use another software just because I have problems.
ask the admin if there is a proxy server in the network you can use to connect. and then change the msn messenger connection options to use either http or socks proxy.
if not, then maybe try socks2http as a local proxy on the computer you wanna use msn messenger on. set msn to use the local socks proxy and configure the proxy as instructed in the readme file. this way it "should" work. video and audio and text will be sent through http on port 80 i would assume through the firewall.
i think you can find the socks2http program as a 30 day trial download. it's small and basically only does what it says it does.
benkol, what firewall does your admin use?

I want to block msn messenger on our network on our pix firewall so maybe he/she can help me (i'm in the UAE).

How to block MSN messenger by firewall
msn messanger uses Upnp as far as I know.
This stands for universal pnp. The software requests a port to be opened but does not specify witch. the firewall forwards directly the port to the software.
if my understanding is correct,
the good thing is only the software (the one that made the original request) will be able to use the port wich is forwarded,
the bad thing is this may be done even though NO rule allows the connection ie u set the firewall to block ALL traffic in ALL directions and you can chat still over msn...

i guess you can easily deactivate this feature from your firewall. of course this would no prevent nonsense's way out. some firewalls (winroute i know of and atguard i herd of) can directly allow you to block specific types of traffic at the protocol level. I guess this could be some help in your situation (they have features such as block *.mpeg, all audio, all chat, all video, all activeX, all Java applets...)

goot luck. hope that was helpfull.
