martin, I apply this patch and set hidden =1,arp_filter =1 too, at all nic's but nothing changed. eth1 always reply that ip 10.0.0.2 is at eth1... It seems be so,that I can't forward packets over two different nic's which are in same network. bye
Roman,
# echo 1 > /proc/sys/net/ipv4/conf/all/hidden
# echo 1 > /proc/sys/net/ipv4/conf/eth1/hidden
# echo 1 > /proc/sys/net/ipv4/conf/eth2/hidden
If you don't have support for hidden in your kernel, visit Julian's page:
http://www.linux-vs.org/~julian/
http://www.linux-vs.org/~julian/#hidden
This will prevent ethernet interfaces from responding for ARP for IPs active on other devices.
Good luck,
-Martin
