[Bridge] Bridge Digest, Vol 36, Issue 8

[Skept]

Julian,

I did not understand what you meant by this paragraph.

"Now, for the twist. For development and testing, I assigned an ip
address and gateway to the bridge. I need to be able for a "non-it"
person to install this box without having to set it up at all , so it
cannot have an ip address assigned, as it *may* be in use somewhere else
on the lan or router."

Did your bridge + transparent proxy work without you adding an ip[\and
route] to the bridge interface? I mean, before the "twist".
