Thanx in Adv.

iptables is the successor to ipchain. I use iptables myself and it IS a very powerful tool for protecting your network.

as for where to get started the 'iptables' command and its man page are a pretty good place to start.

IPTables is really where you are going to set up your firewall rules. IPchains is an older version ised mainly in the 2.2 Kernels, and IPtables is the current version used in the 2.4 kernels. IP masquerading is just a version of NAT that can be set up through IPtables/ipchains.
