Just so you all know I'm not dead or completely immersed in my studies: 
I have just succeeded in converting m0n0wall to FreeBSD 4.9. Sounds 
easy, but due to the countless patches and tweaks required (not to 
mention the various platforms that each need different kernels and 
bootloaders), it isn't all that easy. :)

The next things I'll tackle are finally integrating Petr Verner's 
more-advanced advanced outbound NAT [tm] ;) patch as well as Bruce A. 
Mah's filtering bridge patches (did I make any further promises?). 
Bruce has figured out the cause of the problem that made me use 
ng_bridge instead of BRIDGE in the first place, so we're now ready to 
throw out ng_bridge altogether. Since filtered bridging is quite an 
advanced feature, there will probably be a knob on the advanced setup 
page to enable it. Yes, Bruce, I reconsidered enabling it by default 
and decided against it. :) The reason? I figured that many (if not 
most) people would use bridging to create a wireless access point 
bridged with LAN, and filtering there would harm performance (overhead 
of filtering, tons of state table entries created even with a pass all 
rule, etc.). Besides, such a knob (while not an especially beautiful 
solution, I agree, but so what...) will preserve backward compatibility 
with respect to config.xml. Complaints may be sent to /dev/null. ;)

Besides, an official m0n0wall image for a new platform will be 
released: the Wireless Router Application Platform from PC Engines 
(www.pcengines.ch)! This will be an alternative to Soekris-based 
systems (especially the net4801, as the specifications are very 
similar). I have successfully tested m0n0wall on two beta boards and 
must say that I'm very satisfied with them - excellent stability, "just 
works". Production boards are expected to ship in January. Now you can 
finally have an all Swiss made (well, designed at least) firewall... ;)

Greets,
