We use a dual homed CentOS-6.3 host for our Internet gateway router.
Its internal nic (eth1) is configured such that the address
192.168.0.1 is one of its aliases.
# cat /etc/sysconfig/network-scripts/ifcfg-eth1:192BOOTPROTO=none
NAME="LAN - Non-routable"
Internal packets routed to 192.168.209.41 are passing through this
router out onto the network. I am afraid that the reason is not
evident to me and I have been unable to locate an answer.
The primary address for eth1 has the following configuration:
# cat /etc/sysconfig/network-scripts/ifcfg-eth1
NAME="LAN Link - eth1"
What configuration setting am I missing that will cause packets to
192.168.ccc.ddd to stay on the LAN and not try and pass though the WAN
