Hi all, I have a box with a dummy0 interface and I want eth0 to ignore arps for that interface. All the docs I can find (http://www.austintek.com/LVS/LVS- HOWTO/HOWTO/LVS-HOWTO.arp_problem.html) seem to say set arp_ignore to '1' and arp_annonce to '2'. This however does nothing in my tests. # ls -l /proc/sys/net/ipv4/conf/eth0/*arp* -rw-r--r-- 1 root root 0 Jan 19 14:52 /proc/sys/net/ipv4/conf/eth0/arp_announce -rw-r--r-- 1 root root 0 Jan 19 14:52 /proc/sys/net/ipv4/conf/eth0/arp_filter -rw-r--r-- 1 root root 0 Jan 19 14:52 /proc/sys/net/ipv4/conf/eth0/arp_ignore -rw-r--r-- 1 root root 0 Jan 19 14:52 /proc/sys/net/ipv4/conf/eth0/proxy_arp arp_filter might do the trick but before I dig into source code has anybody already done this and can tell me what I need for a working system? eth0 - 192.168.168.10 dummy0 - <some public IP> I want eth0 to behave as normal and for 'arp who has <public IP>' requests to be ignored by dummy0.
