	I've used Monowall on a Soekris net4801 with 5 ports (using a 2
port card from Soekris) and did do port-to-port routing.  In my case, I
was able to get in the 25-30 Mbit range, if my memory serves correctly,
going NIC to NIC.  That was when the processor in the Soekris pretty
much couldn't handle any more.  You might have 

An Intel NIC might take some of the load off the processor and help the
performance from that standpoint, but I can assure you that it won't
work with the stock Monowall image for a Soekris.  I used an Intel 1000
GT card in a Monowall and had to build a special image to get it to
recognize the card.  

If you are seriously thinking of going the Intel NIC route, I'd suggest
just getting a low priced PC with an IDE interface and get an IDE->Flash
module so you can get rid of the hard drive as a likely point of
failure.  Someone else here could probably point you to a VIA based
system that would do the job well.  I do have a Monowall that does work
with the Intel 4 port MT series card.  (I think the generic version of
Monowall will work with that card, but I'm using a custom build w/ RAID
and SMP support.)

Subject: [m0n0wall] net4801 routing performance

Greetings list,

I know there've been many discussions in the past about the routing
performance of Soekris boxes, but wonder if anyone's done any tests with
7 interfaces. I'm not so worried about raw routing performance between
two interfaces, but I am concerned that the thing shouldn't encounter
excessive delay (latency) when routing between multiple interfaces.

Basically, I need to come up with a router (running m0n0 or pfSense -
undecided at this stage) that'll handle 3 independent LANs (3 companies
in one building), and 4 ADSL connections. The 4 ADSLs will *not* be
load-balanced - there'll just be some custom routing to make sure that
traffic from company A's phone server goes out via ISP A, B via B, etc.
etc., so from a feature-set perspective it doesn't matter whether it's
pfSense or m0n0.

The maximum speed each ADSL's going to hit is 8mbit (and that's unlikely
- 5mbit is more realistic) so raw throughput isn't an issue. There
should be no LAN -> LAN routing between the 3 companies' LANs.

The primary concern here is latency for the phone servers. Oh, one other
quick thing - do folks recommend getting the Soekris-manufactured
4xEthernet PCI card, or is it preferable to get something like a 4-port
Intel Pro/100?

Any suggestions gratefully appreciated. The small form factor and lack
of moving parts of the Soekris appeals considerably, but before I can
use it, I do need to check it'll be up to the task.
