I'm running -STABLE (cvsup'ed on 26jan2001) on a machine with the BRIDGE option, bridging between two PCI NICs (rl0 and xl0). I'm having ARP problems. Machines on the "rl0" card are unable to get a hardware address for the bridge. (For whatever reason, I have no problems talking via the "xl0" interface.) I've done "tcpdump" on the bridge, and it's receiving ARP queries on the "rl0" interface, but it doesn't appear to be sending replies. I did a "tcpdump" on the "xl0" interface too, just in case ARP replies were going out over the wrong interface, but no such luck. If I turn off bridging (sysctl -w net.link.ether.bridge=0), the ARP problem quickly resolves itself. So the problem would seem to be related somehow to the bridge code. I can sidestep the problem by using "arp -s" commands on the other machines to tell them the bridge's hardware address -- but I really shouldn't have to do this. Any ideas?
