Hi, I'm new to iptables and am trying to set up a firewall for my hosting company. We have a block of 128 public ips starting at 207.145.24.128 with a mask of 255.255.255.192. I have a redhat 9 box set up with 2 nics. My goal is to have it between the router and my network. It should allow connections to port 80 for all ips behind it and I would also like to specify certain ports for certain ips for dns, ftp, remote desktop, etc. I've found tons of info on using iptables with nat but not much on just blocking ports for ips passing through it. I'm also not quite sure of how to configure the second nic that connects to my internal network. Any help would be greatly appreciated. Joe
