Any ideas why this rule won't parse?
ipfw add 10 deny ip from \{ not 127.0.0.1 and not 10.12.34.0/24 \} to any 53 out xmit wan0
ipfw doesn't like and and says: ipfw: missing ")"
I've tried other variants, for example, putting the not in front of the brace expression, putting the two IPs in a table and then saying not table(xyzzy)
and nothing will work.
Is there a way to express this with ipfw?
