If you are open to not using CentOS (which is wonderful), I would suggest
something like pfsense.  http://www.pfsense.com/
Based on M0n0wall and I think it will do what you are looking for.   This
would mean you would need a seperate set of hardware however.  As for
hardware, if you have an old machine around, it would probably work.  We use
WRAP boards from PC Engines and they do a great job.
The WRAP board is being discontinued, but the new versions will be out
shortly.  You can still get them at Wisp-Router
Hope that helps!

	My situation:

	I have a cable modem (COMCAST 6Mbit d/l) and am about to also have
DSL (Verizon 3 Mbit d/l).  I was thinking of using CentOS (4.4, 4.5, or 5??)
as a router/dhcp server/firewall for my home network consisting of 3 to 6
computers at any given time.  I seek the wisdom of the members of this list
on the following issues:


	--  Is CENTOS a good direction to go?  I do not mind manually
configuring things or installing lots of packages, and am doing this as both
a learning experience for myself and proof of concept for a customer.

	--  Is it possible/hard/easy/trivial to share the load between the
two connections?  Have either link fail and things still work correctly?

	--  I plan to build a box for this job - looking for general
recommendations of how much horsepower (mem/disk space, etc) is required

	--  What are the implications of two pipes for incoming connections
such as DynDNS based  remote desktop or VNC, or web server, FTP, etc


	The basic hardware layout I see is 3 nics, 1 GB RAM, 60 GB disk
space.  1 NIC for each WAN port, 1 NIC for my local net, some recent CPU.


	I have been browsing through the "Linux Advanced Routing & Traffic
Control HOWTO," but am still not on top of how to get done what I'm looking
for.  I understand that there are probably products that I could buy to do
this, but my preference is to do it myself.


	Sorry if my questions are too basic.  Please feel free to tell me
off if so.  Thanks.
