No, I'm using only one IP address for the bridged pair of NICs. (The IP address is assigned via "ifconfig rl0".) > Can you include the output of 'tcpdump arp' for both interfaces > while doing these cross tests? I'll have to redo my earlier tests and send the results sometime later. From what I remember, though, the bridge machine saw lots of queries ("arp who-has"), but it didn't send out a reply right away. Sometimes, after several minutes, a reply did get sent out, but I have no idea why this happened or what provoked the machine to finally get around to sending an ARP reply. > Been digging in that code the past week, so when I'm done with > some stuff for work I can try and track it down. Can you include > a kernel config and dmesg output? OK. See below.
