Documentation for Laptop Firewall

For those who are interested, here is how I turned my laptop into
a really good firewall:

Here's an e-mail I received regarding this firewall. He's an
independent security specialist. Can anyone verify he's as good
as I think he is (my evaluation is based on other e-mails)?

And so it was. I performed my intrusion test on 7/1/01 starting at 9:16
am.

I found absolutely zero vulnerabilities. It is locked down very well.
