Do I have to have a different set of rules for each one ? msn messenger NEEDS an UPNP enabled fw/proxy get linux-igd (internet gateway device) on sourceforge (http://linux-igd.sourceforge.net/) and the upnp sdk from intel (http://download.at.kde.org/opsys/linux/gentoo/distfiles/upnpsdk-1.0.4.tar.g z). don't use the latest libupnp-1.2.x package, it won't work with igd install (rebuild) upnp from tarball (take care there's a change to do in one of the source files, see igd install text) then build igd from tarball too, this will generate an upnpd executable that you'll have to lauch as a daemon (write your own rc.d script) also take care you need a symlink to iptables (read igd install) or it won't work begin testing with leaving all ports open on the fw, then rtfm and test while closing more and more (it's still a bit fuzzy in my head to know exactly what the strict minimum is to have messenger working...) if you keep the h323 helpers on your gateway, you might have both yahoo or ms-netmeeting and msn working together good luck - * - * - * - * - * - * - Bien sûr que je suis perfectionniste !
