I have done quite a bit of rewriting of my pcbridge code, which is now much more stable than the previously released version (which was quite buggy). Those who want to try it, please get the updated version from my home site: http://www.iet.unipi.it/bdg300.tgz Among other things, I have added buffering of incoming packets, so that now it might become feasible to do bridging between an ethernet and a much slower link (e.g. a serial/parallel port) if someone wants to add the code. Performance is not so bad. On a 486/66 (I can't find 386 anymore!) ping times between two nearby systems increases by 500us for standard-sized packets, and some 5ms for 1500-byte packets (the bridge is store-and-forward). This with ISA boards.
