invert problem with multiport

[Christoph Gossen <gosen@conterra.de>]

Hello,

I think there's a bug in the behaviour of the multiport module - for
example, a line like

        iptables -p tcp -A OUTPUT -m multiport ! --dport 25 -j DROP

causes the same behaviour as

        iptables -p tcp -A OUTPUT -m multiport --dport 25 -j DROP

or

        iptables -p tcp -A OUTPUT --dport 25 -j DROP

and NOT (as one would expect) that one caused by

        iptables -p tcp -A OUTPUT ! --dport 25 -j DROP

Inverting the (set of) port(s) due to the "!" sign in the first line
above is just ignored
(no syntax error occures)!

Any comments?

Thanks,

Christoph
