Hi I built a bridge with: - Linux 2.2.6ac2 - Gigabyte Mainboard - AMD K6/200 - 64MB RAM - Adaptec Quartet (4x100baseT, 21140) - 2GB-HD Quantum bigfoot - Matrox Mystique 200 To test I used 4 Computers directly connected with crossover-cable. The Clients are same class of Computer as above, but with Lantronix NIC (21140) and running NT4SP4 (no comment on NT please. That's what will be used on the clients in the production eviroment...) In general the bridge works, but when the networkload increases, I get up to 100% packet loss!!! I used netperf to test and also just filecopy. A 56MB file took 6 Minutes while the same Operation on the same Computers takes about 20s when they are connected to a cheap Switch... I tried several kernel-options: - optimize as router not host - fast-switching (with patched 8390.[c|h]) - forwarding between highspeed intefaces - CPU is too slow too handle full bandwith (but I never saw a load higher than 10% monitoring using top) I also tried all tests once with all NICs set to full-duplex and once with half-duplex. I would be thankfull for any clues on this matter (even a "forget it. Linux is not usable as a bridge" would be helpfull, as I could then spend my energy on evaluating a Switch).
