Just to let you know, the diff from the currently committed version of
'firewalls' is here:

http://people.freebsd.org/~manolis/firewalls-contrib.diff

Some of these problems are already addressed by the patch I have been
preparing in similar ways.
These are some of your changes that I will try to integrate:

- Exchange "interrogate" with "check" or "match".
- Firewalls may have one or two interfaces
- The comments in the sample rules
- Other various small fixes not already addressed

I am CCing doc- on this, if anyone has any comments please let us know.
I will soon post  a rather long patch for review,  some of these changes
will be included.

Thanks!
