        There are already some *NIX distros that try and provide this
type of functionality out of the box.

        Of course, custom firewalls of any nature are harder to maintain
then a retail product. You can have inter-site VPN's via SSH
http://www.tldp.org/HOWTO/ppp-ssh/. You will 'most likely' have to build
your firewall script from hand, either iptables/ipchains script, or a
shell script. It's viable if you have a dedicated security person. You
will need someone to manage the boxes, update them and keep them locked
down, etc. There is much more maintenance with these servers then say a
PIX or FW-1.

Subject: Firewall Switch

Is it reasonable to switch from licensed proprietary firewall to Open
Source firewall? With budget restraints what they are these days, I
figure I can step up and offer to convert the impending expiration of
current hardware/license. The proprietary firewalls currently in place
number 7 and protect key internet points at 6 geo-locations. Current
support licensing is past $10k per. The firewall technology itself
purports application layer, although much of the newly needed http/xml
stuff is not yet implemented.

Would I be able to provide the same level of protection and prove same
to managers? Would I really save dough? Also site-to-site vpn is in the
mix betwixt all sites...any thought appreciated.
