kern/97504: [ipfw] IPFW Rules bug

[Oliver Fromme]

Hello Marcelo,

I just stumbled across this old PR which is still open.
Apparently the problem was caused by missing DNS access,
not a bug in IPFW itself.  Note that DNS queries often
happen "behind the scenes".  Even if you use IP numbers
only, many programs will try to perform reverse-lookup.

Do you agree that the PR can be closed?

Best regards
   Oliver
