Almost forgot - diff need ot be appied only on FreeBSD 5 version of 550.ipfwlimit,
but resulting file can be used on both 4 and 5 releases.

Better version then previos, it will not break order of rules.

awk version, it will work on all 4 and 5 releases, at least those, where IPFW enabled ;-)

Also i removed check for digit+space+digit - it can break things if ipfw output will be significally changed.

diff -u 550.ipfwlimit 550.ipfwlimit.new
