Hi Rob, > I think this is a good read : > http://iptables-tutorial.frozentux.net/iptables-tutorial.html I've to agree years ago I was reading this howto but the chain rules above were out of the simple firewall script from Oscar Andreason and it's not documented why it's to __DROP__ a packet. It's a very good howto ! I've read also the manpage and I'am reading a firewall book at the moment but it's not concerning to a specific DROP after two other rules so I asked to comprehend my firewall script in order to understand it completely. -- Best Regards, Mark
