Touse the audio/video functionality of MSN Messenger (or WindowsMessenger, but I will use the former term in the rest of this article)through a firewall, you need UPnP on your firewall. This articleexplains how to add UPnP to your Linux kernel 2.4 based firewall (forexample SmoothWall 2).It took us some beers and a substantial amount of frustrating hours tocollect the proper information and set it up. This article will turnfrustrating hours into a handfull of happy minutes... Well, if you likebeer.Some knowlegde about networking and Linux is required. We usedWindowsXP and MSN Messenger beta-5, build 527, but it should also workwith other Messenger versions. We're not sure if UPnP will work withother Windows versions (probably not, maybe there is an UPnP updateavailable).What is UPnP?UPnP stands for Universal Plug 'n Play. It allows some clients withinthe internal network to open up your firewall, when needed. Note thatthis is a security issue. Refer to http://www.microsoft.com/windowsxp/pro/techinfo/planning/upnp/default.asp for info about UPnP under WindowsXP.Collecting the correct softwareTo install UPnP on your firewall, you need . As the site explains: Thisproject is a deamon that emulates Microsoft's Internet ConnectionService (ICS). It implements the UPnP Internet Gateway Devicespecification (IGD) and allows UPnP aware clients, such as MSNMessenger to work properly from behind a NAT firewall.

Download gateway-0.75.tgzor a newer version. LinuxIGD only works with kernel 2.4 (iptables). Ifyou are looking for something for kernel 2.2 (ipchains), check out http://pseudoicsd.sourceforge.net/.

LinuxIGD needs the http://upnp.sourceforge.net. Download upnpsdk-1.0.4.tar.gz or a newer version. Do not download the rpm, because you need to make some changes in the code.Follow the instruction in the INSTALL document of LinuxIGD. You have tochange something in the code of the UPnP SDK, you have to compile itand you have to compile the LinuxIGD UPnP Daemon.... or....

... or forget the above and download our already by RuweBit compiled files !! Is compiled for kernel 2.4.17.Move the files to the correct placesIf you downloaded the RuweBit package above, or compiled it on anothermachine, follow the next steps to move the files to the correct places
