Join us at UAT.edu as we build and play with Firewall ISO's in old boxen with
network cards.
Just imagine the script kiddies surprise when your new Firewall retaliates with
a storm of SYN packets automagically rather than roll over like your Linksys or
Netgear did?
Imagine being able to check snort logs and dump a big list of IPs directly to a
deny file without having to type them all into teensy little forms like on the
http://192.168.1.1/filters.htm screen!
Addicted to the LinkSys/Netgear Wireless, or like the fast ethernet ports and
pretty blue and white LinkSys interface for setting up VPN's?
You can set that device in place on the INSIDE of your Firewall of China!
See you there!

Yes, I was thinking about getting an ASA, but I like my gigabit 1000BaseT
connections, L2 vlan, VPN's, and I think you are correct that optimally, a fast
machine with 4 ethernet cards is going to be the direct solution in line before
that silly "LinkSys" arm processor IPS.
I used to build custom linux firewalls in 1995 and drop them in for businesses
with a 2400 cisco, and I have built a few since (azwsx.com) so I think I will
take your advice - I have a fresh install FreeBSD box right here, and a couple
extra cards.
Thanks for the great suggestion!
