Question about nat filtering with FORWARD

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi there,
I use to do nat filtering with the PREROUTE chain, but in the latest
version i see that is no longer possible.
After trying to ajust my scripts i did:


#allow TCP PORT 22
iptables -t filter -A FORWARD -p tcp --dport 22 -j ACCEPT # ssh
#block everything else
iptables -t filter -A FORWARD -j DROP


Am i doing it in the correct way?
The problem is, i cannot access the 22 port to the outside world when the
DROP rule is applied.

Jorge,
