For now I can't find the original to edit and scan.
If it doesn't turn up next week, I'll make a fresh diagram.

Yes. Addresses 142.103.107.137/25, 142.103.107.138/25, and 142.103.107.139/25
are for my use. 142.103.107.139 isn't involved here of course.

http://wiki.debian.org/BridgeNetworkConnections is also helpful.
A detail I still wonder about is the configuration for eth1 on
dalton. Can it have an arbitrary static local address?
allow-hotplug eth1
iface eth1 inet static
address 172.24.2.1
netmask 255.255.255.0
"Arbitrary" meaning that 172.24.2.1 is any local address which
doesn't interfere with another interface in the LAN.
Logically speaking, this stanza really shouldn't be necessary,
given that the br0 stanza includes eth1 as one end of the bridge.
I suppose it must allow a simplification of the algorithm which
makes the bridge.
Thanks, ... Peter E.
