Hello,

Então não adiantou usar essa regra não. Ele simplesmente nem passa
pela Regra. Olha como ficou a ordem:

/sbin/ipfw -q -f flush
/sbin/ipfw add 65 fwd 10.5.1.1,3128 tcp from 10.5.0.0/16 to any dst-port 80
/sbin/ipfw add 80 divert natd all from any to any via lnc0
/sbin/ipfw add 90 check-state
/sbin/ipfw add 95 allow all from any to any via lo0
/sbin/ipfw add 100 allow log icmp from any to any
/sbin/ipfw add 200 allow ip from 10.5.0.0/16 to any keep-state
/sbin/ipfw add 250 allow ip from any to 10.5.0.0/16 keep-state
/sbin/ipfw add 65000 deny all from any to any

Acho que vou deixar pra lá. ehhehe
Valeu
