I've got all the necessary options enabled for ethernet bridging and ipfw, and the desired scenario is working. There are several problems at hand here. The first is something that popped up after the initial FreeBSD installation. I have a pair of 3COM NICs (xl driver) in the machine. Periodically, I'll get an error along the lines of: /kernel: xl1: transmission error: 90 /kernel: xl1: tx underrun, increasing tx start threshold to 240 bytes I'll intermittently get errors like this for bother interfaces. This problem is independent of the ipfw/briding configuration. The second problem I'm running across is another kernel error message (this is with bridging and ipfw in a working state): /kernel: collision at 5378 What can I do about this? Also, when pinging hosts, I'll also occaisionally see a ping reply along the lines of: 64 bytes from xxx.xxx.xxx.74: icmp_seq=407 ttl=255 time=0.514 ms (DUP!) What is the cause and solution of the "DUP!"? Next, how does net.link.ether.inet.proxyall tie in to all of this, as it seems that my bridge will not function without it? I know there are a lot of questions/topics covered above, but if anybody can provide me with any leads to explore on any of the above, I'd very much appreciate it.
