FW: Help needed for IPTABLES



 
All experts Hi,
 
I try to secure a RedHat ES 3.0
I have two NIC's etho and eth1.
 
I want to at the begging to drop everything on eth0 and accept only what i need like SSH.
 
I use this rules
 
iptables -A INPUT -i lo -p all -j ACCEPT
iptables -A OUTPUT -o lo -p all -j ACCEPT
iptables -A INPUT -i eth0 -m state --state ESTABLISH, RELATED -j ACCEPT
 
for dropping all connection i use this rule
 
iptables -A INPUT -i eth0 -p tcp --tcp-option ! 2 REJECT --reject-with tcp-reset
 
for accepting i use this rule
 
iptables -A INPUT -p tcp -i eth0 --dport 22 -j ACCEPT
 
basically i stop all connection but it effect booth eth0 and eth1
and for port 22 i can't connect , surprise when i run   iptables -L -v  i get  as SSH connection was accepted.
 
at the same time i found that the output connection like internet do not work.
 
i need help on this issue.
 
Thanks
Hari
