I'm running -STABLE (cvsup'ed on 26jan2001) on a machine at home
which I've configured as a bridge (options BRIDGE).
After some problems with a PnP ISA network card ("ed" driver), I'm
running more or less successfully, bridging between two PCI NICs
("xl0" to the Internet, and "rl0" to an internal network).
Now, though, I'm having ARP problems. A machine on the "rl0" NIC
is unable to get a hardware address for the bridge ("arp -a" shows
the bridge's ARP entry as "incomplete").
If I turn off bridging (sysctl -w net.link.ether.bridge=0), the
ARP problem quickly resolves itself and the two affected machines
can talk to each other. So the problem would seem to be related
to the bridge code.
For whatever reason, the bridge is having no problems talking over
its other interface (xl0).
I can sidestep the problem by doing an "arp -s" command on the other
machine to tell it the bridge's hardware address -- but I shouldn't
have to do this.
Any ideas?
