My company is in the process of connecting to the Internet through one
of the commercial providers. We've contracted for a 9.6 Kbps metered
service (at least initially). We will design and build a firewall
prior to coming online. I just attended Brent's seminar on building a
firewall and am now looking for some advice.
We are going to use a Telebit NetBlazer PN-1 for the external router.
Why? It was VERY aggressively priced. Also, it is a nice inexpensive
match for our low speed connection today. If we go faster in the
future, it will be replaced.
Now I need an internal router between my peripheral net and interal
net. I have 2 registered Class C networks (1 for peripheral, 1 for
internal).
What router can you recommend to use for the internal router?
I am considering 2 options now, but others will be considered.
1) Telebit Netblazer ST with 2 ethernet cards
Pro: don't need to learn new filter specification language
2) PC running BSDI with screend
Pro: better routing algorithms
Con: 1 more filter spec language to learn, more system
configuration
I'm assuming that both 1 and 2 will cost about the same (~$3500).
Can anyone give me some insight? I also don't know some fundamental
things like: Is screend bundled with BSDI? Do they support it?
Also if someone could send me the proper Ethernet cards to get for the
BSDI machine, I would be appreciative.
If particular vendor recommendations are inappropriate for the forum,
please mail me directly.

ps. I don't yet have Internet access -- so thank you for pointers to
documents out on the net they are appreciated -- but I can't readily
download them. I have the Firewalls-FAQ.
