Stop macro:
$IPT -N LD
$IPT -A LD -j LOG
$IPT -A LD -j DROP

$STOP=LD (LD = Log and Drop)

$IPT = /sbin/iptables

I need to totally block all packets to and from this address 64.246.26.185. So BLOCK means BLOCK.

We OpenBSD users usually mean blocking as dropping the silly thing on the floor. No ifs, ands or buts. Just gone...

As for the limiting, I simply copied a rule that was already in a firestarter script. So if I need to change the rule, I would be more than willing. Am I to assume that this is a bad rule?

tx for the assist.

What do you mean by "block"?

1. Stop packets from that address getting in to your firewall?
2. Stop packets from that address going through your firewall?
3. Stop packets to that address coming from your firewall?
4. Stop packets to that address going through your firewall?
5. Some combination of the above?

What does the $STOP macro expand to?

Also, the above rules are rate limiting rules - they will prevent packets 
flowing more quickly than you specify - that is not at all the same thing as 
blocking packets completely.

Tell us more precisely what you want to do (see above) and we can probably 
advise on how to do it.

Antony.
