Package: ebtables
Version: 2.0.6-3
i'm using ebtables 2.0.6-3 (from stable debian distribution) to make a brouter.
Here are the rules used:
ebtables -t broute -A BROUTING -p ipv4 -i eth1 --ip-dst 10.70.12.102 -j
redirect \
--redirect-target DROP
ebtables -t broute -A BROUTING -p ipv4 -i eth0 --ip-dst 10.50.22.102 -j
redirect \
--redirect-target DROP
ebtables -t broute -A BROUTING -p arp -i eth1 -d 00:12:3F:20:D8:E2 -j redirect \
--redirect-target DROP
ebtables -t broute -A BROUTING -p arp -i eth0 -d 00:12:3F:20:D8:E1 -j redirect \
--redirect-target DROP
ebtables -t broute -A BROUTING -p arp -i eth1 -d broadcast --arp-ip-dst
10.70.12.102 -j \
redirect --redirect-target DROP
ebtables -t broute -A BROUTING -p arp -i eth0 -d broadcast --arp-ip-dst
10.50.22.102 -j \
redirect --redirect-target DROP
ebtables -t broute -A BROUTING -p ipv4 -i eth1 --ip-src $RX_INTERNE -j redirect
\
--redirect-target DROP
When i want to make an arp broadcast from this brouter with arping for example
arping -B.

Could you explain me if it is a bug or an error of utilisation?
Here's the /etc/network/interfaces file:
