My meaning was this one. In case you want to enforce mac comparison
it is better working in pf.conf on the interface with *portable* rules
like this one than going on specifying mac addresses here or there:

pass in  on $ext_if proto tcp from any to any port 25

Indeed, I see, portability is an hard to obtain status also in pf, when the if 
change.

Do you have a more effective as *portable* tip in respect to this subject and 
pf?
