I think dhcp acts beyond the eth0/192.168.1.226 wireless bridge. Somehow
I have to direct the computer to that eth0 interface if it's going to
reach the internet, printer, etc.
As you say you can't know what my system looks like but I think what I have
now is pretty close to being set up right and it is working again,
thanks to the help
I received here.

I don't think the last line is correct as above. 10.1.1.1`box1 should
be eth1
while 192.168.1.226 is eth0 that connects to the wireless bridge. Perhaps
as you say I should have named them differently somehow but I tend to think
of them as interfaces to the same computer, box1. Box1 has to
interface either
the LAN or the wireless network.

Ok, I won't try that.
I appreciate the time and effort spent covering this for me.
Thanks.
