I've just setup a P75 system as a router, containing fa311 and pcnet network cards. The fa311 is doing nat to my private network, which is served by the pcnet card. However, I've found that it often uses 40% cpu just to send packets from the fa311 (sis) to the pcnet (lnc) cards. natd uses 20%, 10% are interrupts, and 25% is 'system' as shown in top. Also, I'm getting several thousand 'lnc0: Missed packet -- no receive buffer' messages. Could this be the problem, or is the system just not powerful enough do nat? The sis0 card is 100MBit PCI, while the lcn0 is 10MBit ISA.
