>Description:
The natd option -punch_fw won't work with kernel securelevel 3

This is really a feature of securelevel 3.
>How-To-Repeat:
Setup working natd -punch_fw at securelevel 2 or lower on the firewall
Go to securelevel 3
Attempt active FTP from client inside to outside, fails.
>Fix:
"Fix" is to add a note to the natd man page under the -punch_fw option
that securelevel 3 will disable punch_fw.

Long term:  If ipfw can add dynamic "keep-state" routes in securelevel 3,
why can't the NAT function?  Note I didn't say natd here.
