Well, I managed to get this to work, almost completely
the way I want, but its taken alot more not-easily foudn
steps to get there.
I bumped into a link to a microsoft KB article about how
bridging might not work if the NIC's are not
in "promiscuous" mode. You have to use the netsh utility
to put them in this mode if they are not. I did this for
both adapters, and suddenly I have my IP back on the
bridge computer. However, the new PC cannot get an IP
address using DHCP. So I give it a static IP address in
the same subnet as everybody else, copy the DNS servers
IP addresses too, and wow, everything works.
EXCEPT: When I ask my router what clients it sees, it
will report the IP address of the bridge PC, with its MAC
address, but the name of the new PC!. This is probably
why DHCP won;t work: I assume that the DHCP server
decides that it cannot give out two IP addresses to two
clients with the same MAC address. BUT, why does the
bridge not pass through the MAC address of the new PC,
separately from the MAC address of the bridge PC? Again I
can find no documentation for this anywhere.
The Knowledgebase artical that describes how to check and
put the NIC's into promiscuous mode is artical number
Q302348.
