Heh. Sounds like your home network is more of a daisy chain of computers with multiple network cars in them or something else equally as strange.

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

That's because it's not a package per say. Proxy ARP is a feature of the kernel that has to be enabled, much like routing and IP forwarding.

Rather than me re-typing how to do it, take a look at the write up about it in the Linux Advanced Routing and Traffic Control HowTo - Pseudo-bridges with Proxy-ARP (http://lartc.org/howto/lartc.bridging.proxy-arp.html).

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.
