Well, the whole point of an ethernet bridge is that the interfaces
bound to it do  not have an IP of their own - they use  the IP of the
bridge.  Normally one wouldn't specify the interface itself at all in
the interfaces config, but I needed to supply the wireless essid.

I did try using 'manual' method for the ifupdown declaration, but that
didn't work either.

For security reasons, I insist that wireless cards have static IP addresses.

I've tried ditching the Debian configuration mechanism altogether and
doing the whole lot manually.

$ brctl addbr br0
$ brctl addif br0 eth1
$ ifconfig eth1 0.0.0.0
$ ifconfig br0 10.0.0.110
$ iwconfig eth1 essid unsecured
$ route add default gw 10.0.0.138

Iwconfig shows eth1 has a signal, ifconfig shows the ip details, and
the routing table is correct.  But I still cannot connect to any
machine on the subnet.

Upon removing the bridge and configuring just eth1, it works.

What am I missing?
