imho the most secure way is to add an entry to sudoers(5) (you can use visudo(8) to edit sudoers(5)) allowing the apache privilege-separation user (www? we use apache here -- check your httpd.conf for "User") to execute that specific command without a password. The entry might look something like this:

apache ALL=(ALL) NOPASSWD: /sbin/ipfw

That will allow the apache user to do things like:

	sudo ipfw table 7 add …

because sudo will allow password-less privilege escalation to root (but only for ipfw, nothing else, for security reasons naturally).
