Perhaps you should be doing your homework first. IPSec is not a firewall. Microsoft does have some firewalling abilities, but that is not IPSec. IPChains is also far from "full featured", and is dead and buried with the 2.2 Linux Kernel.

From the Wikipedia: "IPSec (abbreviation of IP security) is a standard for securing internet protocol communications by encrypting and authenticating all IP packets."

It mentions nothing about the ability to be used as a firewall.

The full article: http://en.wikipedia.org/wiki/IPSEC

Read up on IPSec before you post next time:
http://www.ietf.org/html.charters/ipsec-charter.html

If you are going to berate someone, at least know what you are talking about.
