I would design some kind of sniffer instead of a router. In this case you
save a lot of cpu load because you don't have to copy every word from one
interface to the other. You can do a lot of statistics with it (I would like
to find who is causing the packet jam at 11:45 and 16:45 every day in our
office) Or you could put two uCSimms together using the unused iopins, this
would also need a nice concept to split the load on the two ups.
