Pls Help - Rule in IPTables

[menonrr at jmu.edu]

Hello,

I have a Linux Redhat 9 gateway that is used for internet
sharing. Remember that I am a new user to IPTabels and Linux.

I would like to configure the IPTables so that no new
connection can be established from outside to the Gateway.  

Network set up: Internet ---- ||eth1 |134.public-IP "Gateway"
192.168.1.10 |eth0 ||----- inside

Is this rule good rule?

iptables -A INPUT -s 0/0 -i eth1 -d 134.Public-IP -p tcp -m
state --state ESTABLISHED, RELATED

Thank You
Menon
