Of course it would be rather unreasonable to expect that a box with a single ethernet would be pushing through more that the aggregate bandwidth of the serial lines, considering that you wouldn't likely be using this router for any services. That should max out the Ethernet at 48Mbs if you had no serial-serial traffic. This implies that FreeBSD would have to be able to "route" 48Mbs, which is somewhere between 10,000 and 15,000 pps. Doable, I think. db
