This rule will redirect any traffic from 10.*.*.* trying to reach 
port 80 through the qube to port 8080 instead.

/sbin/ipfwadm -I -a acc -P tcp -S 10.0.0.0/8 -D 0.0.0.0/0 80 -r 8080

ipfwadm will do the task for you, just not through the UI.  I
suggest you thoroughly read the ipfwadm man page before working
with it.  You could lock yourself out of the qube.  But thankfully
there is the 'reset filters' available on the menu if you get 
yourself into trouble.
