A followup: I forced a reset to factory defaults (by holding down the
"ADD" key and cycling power) and the problem I encountered with DHCP
disappeared. DHCP worked fine.
Then I turned on Ethernet/WiFi bridging, and the problem appeared again.
Neither the Squeezebox nor the Powerbook I have plugged into the
Ethernet port on the Squeezebox can do DHCP.
I see some broadcast traffic from my wireless network coming through on
the Ethernet on the Powerbook, but I can't seem to connect to anything
on my home network with either IPv4 or IPv6.
Packet traces at the DHCP server seem to show that the Squeezebox is
writing its own MAC address over the source address fields of the
packets it is relaying from the Ethernet, something a bridge shouldn't
do (bridges are transparent to MAC frames). And when bridging is
enabled, the Squeezebox's own DHCP packets have the correct MAC address
in the Ethernet link level source address field, but carry a bogus MAC
address in the DHCP application-level packet so the Squeezebox doesn't
hear the DHCP server responses.
Basically, it appears that Ethernet bridging is completely broken, and
enabling it disables the Squeezebox as well.
Again, this is firmware version 28 on the Squeezebox 3.
