[plug] Help with IP Tables

I need some help on writing a firewall rule for letting in and out on port
 5721.
 Are you able to write this?

 eth0 is Internal
 eth1 is External

What I have is an INPUT and OUTPUT rule that simple states:


 $IPT -A INPUT -p tcp -i $INT_IFACE --dport 5721 -j ACCEPT
 $IPT -A INPUT -p udp -i $INT_IFACE --dport 5721 -j ACCEPT


I've also allow this port out of the Cisco Router that sits in front of
the Gateway server where these rules are applied.
