need help with pf configuration


I have a configuration with 2 inside interfaces, 1 outside and 1 dmz
interface. The traffic should be able to flow

1) from inside1 to any (and back)
2) from inside2 to any (and back)
3) from dmz to outside only (and back).

I need no details, just a general hint how to setup such security
levels, preferably independent of actual IP addressses behind the
interfaces (a :network macro is not always sufficient). It would be
nice to find a configuration that would scale to any number of
interfaces with different security levels.

On a Cisco PIX I would configure

outside security0
inside1 security100
inside2 security100
dmz security50

and that's it, the PIX logic would do the rest.

Thank you very much in advance for any input.
