Just for fun, a '486 with 2 pci ethernets and a dual t1 card can handle full 10Mbs on both ethernets and full-duplex full T1 on the serial port simulatanously. Pretty snazzy, dont you think? PC cost, less than $1400. If you're really the hardware guru you say then you know how a 25XX dual ethernet fares in this test........ > >>>C'mon guys, use the right tool for the job.

Just >what *are* you saying? you're the one that said that "PCs cant replace routers". Is a 25xx not a router? Your definition of a router changes from paragraph to paragraph. Maybe thats the problem.
