Hi Ranjith,

In my case, rp_filter does not change anything. I'm going to try it on
centos 7 now that it's out, but this can take several days before I can
set the vm for testing.
What I can tell is that I either get the reply with the nic mac address
or don't get any reply (all.arp_ignore=1) but I can see the who has
comming from the net by using tcpdump (with all.arp_ignore=0):
