[bwm-tools-tech] Harware requirements? - iproute & tc like?

[<gb...@hq...>]

Hello!

I've a couple of basic questions I assume anyone with experience with bwm
tools will be able to answer.

I've done near six years ago a linux fw with five ethernet cards:
2 lans, 1 dmz and 2 internet prooviders. What I did at the momment was
read linux advanced routing how to and the little documentation I found at
that time about using iproute and tc to proovide advanced routing and
rationalize traffic usage for each route besides a small script to keep
lans & dmz always connected if one of the internet lines got down or each
lan on a different internet line if both were online. Well.. this setup
went ok and worked like a charm.

Now I've a less ambition project, setup a firewall with four ethernet
cards on it: 1: Internet line. 2: First lan. 3: Second lan. 4: attach a
wireless AP.

So now comes the questions:

1.) Is bwm tools capable of proovide me in such a setup all the flexibity
I need to build my iptables rules as however I want it through ethernet
cards and IP based and the same ability to build any trafic shapping
rules?

2.) I tryed to search the mailing list and I found some people complaining
packets were lost and someone else asking if this was not because the
hardware was not poweful enough to handle all the data.
So the question is, in such a setup as I want to do, what you people
suggest as a minimum hardware (cpu, mem) keeping in mind that the linux
machine will be doing nothing else except running bwm tools & sshd?.

Best regards and thank you for your time
