Try this:
in /etc/ppp/ppp.linkup
dialup_isp_label:
/sbin/ipfw add XXX fwd HISADDR tcp from any to any 25,53
/sbin/ipfw add YYY fwd HISADDR udp from any to any 25,53
^^^ numbers depends of ^^^ if you have own dns and/or mail
others ipfw rules server change with ip address
that they are bind
in /etc/ppp/ppp.linkdown
dialup_isp_label:
/sbin/ipfw delete XXX
/sbin/ipfw delete YYY
Remove or comment "add default HISADDR" in dialup_isp_label section in
ppp.conf and set default route to cable connection .
