Build a router with a controller
Archiver

Hi everyone,
This might be a message to wrong group, but how difficult would it be to build
a router with a micro? I've been sharing cable internet at home with a few
computers and one acts as the server assigning the IP addresses. It occurred to
me that I was wondering if a microntroller could do the same thing as well as
route packet requests in and out. I'm not talking about anything high
performance but fairly simple.
Thanks,
Thomas

This is essentially what the chipset is doing on a 10/100/1000 NIC. You
"could"
do it but you probably won't get the speed even close to what you are currently
experiencing without a custom chipset.

for about as much as a BS2 would cost. But if your after the challenge of
building it, go for it.

If you just want a router, you can get a nice router/hub for around $60 at
your neighborhood computer store. I just installed a SMC device for my
daughter's DSL and it is working like a charm for two computers.
If you just want to build a router, I'd suggest Linux. Any old 386 or 486
computer can do the job. Its possible to do this without a hard disk, but
for a beginner I'd suggest a reasonable HD and a standard distribution (like
Red Hat). This would be a bit of challenge for your first network, but I
think its doable by any motivated technophile.
Building a router from components would require developing a lot of know-how
about hardware and software. There are some very small boards with the
required Ethernet interfaces and protocols, but even starting there it would
be a fair amount of work. I'd bet that most 4th year CS/EE students would
consider this a significant challenge.
