I am trying to implement the verrevpath suggestion in the ipfw man page, as follows: > The verrevpath option could be used to do automated anti- > spoofing by > 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! -- Mark Edwards
