I am trying to implement the verrevpath suggestion in the ipfw man

The verrevpath option could be used to do automated anti-

adding the following to the top of a ruleset:
ipfw add deny ip from any to any not verrevpath in
However, when I try to add the rule, I get an error:
lilbuddy:~ paimin$ ipfw add deny ip from any to any not
verrevpath in
ipfw: unknown argument ``not''
Can someone tell what is causing this syntax to fail? Thanks!
Works fine for me right now on -STABLE (RELENG_6).
You didn't mention what you were running, so there's not much else we
can tell you.
Sorry, I am running 4.11, and nothing weird that I know of that would
affect ipfw operation.
I found a posting via google from someone with the same question, and
then he replied to himself that reading the man page had given him
the answer, but he didn't say what that answer was. Tried to email
him, but it bounced because my mail gateway doesn't have an SPF
record so his server rejected my mail (even though my server DOES
have an SPF record -- ugh).
Thanks!
