thank you very much for your help Shyam. Unfortunately, this parameter doesn't help my eth2 to ping # sysctl -p net.ipv4.conf.default.rp_filter = 0 net.ipv4.conf.all.rp_filter = 0 # ping -I eth2 192.168.15.1 PING 192.168.15.1 (192.168.15.1) from 192.168.15.12 eth2: 56(84) bytes of data. >From 192.168.15.12 icmp_seq=2 Destination Host Unreachable >From 192.168.15.12 icmp_seq=3 Destination Host Unreachable >From 192.168.15.12 icmp_seq=4 Destination Host Unreachable -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
