This is a very good point of view of my topology. But offtopic.

I will read that soon.

For now, i have tested parprouted (see message dated 22/07/08 18:01 
(west Europe)). Fact is: it solves the arp problem at one condition: I 
have to shutdown completely the bridge.

parprouted does not work at all with br0; it works properly only for 
eth0+wlan0_rename ... and only when br0 is off ("brctl delbr br0"); 
then, all ARP tables are set up as desired (real mac of the machine 
within the segment; IPs of machines from other segments are aliased to 
Gluton's MAC). Et the time i do "brctl addbr br0 && brctl addif br0 
eth0", arp resolution stops working (after cache expiry, or manual 
deletion).

So, my problem is not to get the right arp resolution, and find a way to 
bridge interfaces so that it wont prevent arp to work as required. This 
is an offtopic problem for now; i have a new path to walk, and i got new 
ideas for google keywords to search for. I ll give feedback in few days 
(either giving a solution, or with new problems :D ). I have to find why 
parprouted and brctl seem incompatible ... or how people do the bridging 
when using parprouted around ...

I am open minded for changing the software approach, as long as we keep 
trying to use my actual hardware.

I now have things to work on my side.
