Help w/ Iptable Rules

[<fbrian@nac.net>]

Hi

I need help w/ simple iptables rules.

Needs:
	to only allow ssh packets in and they would be over an
	ethernet interface.

	allow all outbound traffic

Rule set I am working with.


     iptables -N block
     iptables -A block -p tcp --syn --destination-port 22 -j ACCEPT
     iptables -A block -p tcp --syn -j DROP
     iptables -A block -m state --state ESTABLISHED,RELATED -j ACCEPT
     iptables -A block -m state --state NEW -i ! eth0 -j ACCEPT
     iptables -A block -j DROP


     iptables -A INPUT -j block
     iptables -A FORWARD -j block

TIA

Brian
