Messenger uses port 1863 tcp for communication, and some HTTPS SOAP requests to M$ servers.
You need to block this port using iptables.

iptables -A FORWARD -p tcp --dport 1863 -j DROP
iptables -A FORWARD -p tcp --sport 1863 -j DROP

Hi Guys,
I've a running a  transparently working  copy of squid 2.6 stable 19 on a
Linux FC9 box.
I wanted to block msn/windows live messenger through it, i've add following
code in my squid.conf

acl msnmime req_mime_type ^application/x-msn-messenger

acl msngw url_regex -i gateway.dll

http_access deny msnmime

http_access deny msngw

but messenger is still signing in...

Does any body have another solution?


Regards
