OK, I could use this:

	my_services=" or"

But is there a more convenient way to do this?

Hi Bill,

thanks for the quick response (as usual ;)).

Yeah, concerning logging I use log 1 and log 2 at the moment that
logging traffic to ipfw1 and ipfw2 interfaces respectively.

BTW, I want to use this list feature in conjunction with a specific
destination port like this:

ipfw3 add allow ip from x or y to a or b dst-port 445 via igb1

This syntax does not work. I also tried: port 445, ports:445, 445 and
:445. Nothing is accepted by ipfw3.

What would be the line to use?
