Put
net.ipv4.conf.all.arp_filter = 1
into your /etc/sysctl.conf
and run (for the time being)
sysctl -w net.ipv4.conf.all.arp_filter=1
Linux implements the weak host model, so packages are accepted on any
interface, *if* the traffic is directed at the host.
When arp is used, this model doesn't always work. That's why you should
use the sysctl setting above.
Cheers,
Ralph
