Perhaps I should give some more info. It is a two-gateway machine. I have following lines in my rc.local: # routing and default gateway for each interface ip route add 10.0.0.0/24 dev eth0 src 10.0.0.32 table T1 ip route add default via 10.0.0.11 table T1 ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2 table T2 ip route add default via 192.168.2.1 table T2 # regular routes ip route add 10.0.0.0/24 dev eth0 src 10.0.0.32 ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2 # default gateway ip route add default via 10.0.0.11 # rules ip rule add from 10.0.0.32 table T1 ip rule add from 192.168.2.2 table T2 But again, the system was working before fine. The problematic interface is 192.168.2.2 (eth1). In network-scripts directory, I have 2 eth configuration files, nothing else (apart from lo of course). eth0: DEVICE="eth0" NM_CONTROLLED="yes" ONBOOT=yes HWADDR=52:54:00:E0:5A:C5 TYPE=Ethernet BOOTPROTO=none IPADDR=10.0.0.32 PREFIX=24 DNS1=127.0.0.1 #DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System eth0" UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03 PEERDNS=no eth1: DEVICE="eth1" NM_CONTROLLED="yes" ONBOOT=yes HWADDR=52:54:00:B5:B6:D1 TYPE=Ethernet BOOTPROTO=none IPADDR=192.168.2.2 PREFIX=24 DNS1=127.0.0.1 #DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System eth1" UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03 PEERDNS=no network: NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=www.onart.com.tr GATEWAY=10.0.0.11 Thank you for your support.
