arp

client (IP = 1.1.1.1) - bridge (brctl) - server (IP = 2.2.2.2) (all machine are Ubuntu).

The client block arp request. (there are multiple clients ) I need to define a rule on the bridge machine that will return the client MAC when it get ARP request for IP 1.1.1.1.

I see that in ebtables there is an arpreply option , but i didnt manage to find an example to define the arpreply by given arp request ip.

ebtables -t nat -A PREROUTING -p arp -j arpreply --arpreply-mac 00:09:5B:91:56:08

Can you please adcive
