When this line is run
/sbin/ipfw add pass tcp from any to {$oip} 25 setup
I get:
ipfw: error: extraneous filename arguments
usage: ipfw [options]
[pipe] flush
add [number] rule
[pipe] delete number ...
[pipe] list [number ...]
[pipe] show [number ...]
zero [number ...]
<SNIP> Continuing syntax suggestions from ipfw including established/setup
option..
however, when the word 'setup' is dropped, the rule is added to the set.
Very puzzling, I get the same error when I try to load the default rc.firewall
script which came with the package. I am about ready to set up another system
and retrace my steps to see where the conflict came in.

the natd line is 2nd in the set after the flush command
/sbin/ipfw add divert natd all from any to any via xl0
xl0 being the external NIC; vx0 the internal LAN
ps reports natd is running with the -n flag on xl0
