There are two standalone alternatives for that, my pcbridge code (available from my web page, romable, but only supports ed-like cards) and the drawbridge stuff at http://drawbridge.tamu.edu/ Both are based on FreeBSD (pcbridge actually only uses the netboot code, but compiles under FreeBSD). remember, acting as a bridge puts a lot of load on a machine because it has to listen to all traffic on all interfaces. pcbridge saves some work by only loading to memory the header of the packet and throwing data away if the packet must not be forwarded, but a solution using the generic FreeBSD device drivers would almost surely have to load the entire packet to memory before working on it. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
