Use either the "me" pseudo-address or trigger on the interface. A few 
rules copied out of my current ipfw configuration:

00600 allow tcp from me to any setup
01400 allow udp from me to any dst-port 53 keep-state
01500 allow udp from me to any dst-port 123 keep-state
01600 allow udp from 67 to me dst-port 68
01700 allow udp from me 68 to dst-port 67

The human mind ordinarily operates at only ten percent of its
capacity -- the rest is overhead for the operating system.
