I've backported that ipnat source port randomization patch to  
m0n0wall's FreeBSD version (6.3-RELEASE), and also made a relatively  
important bug fix along the way (see <http://marc.info/?l=ipfilter&m=121709678805631&w=2

It'll be in 1.3b14 (with a setting on the System: Advanced page to  
control the port range, in case anyone desires to do so).
