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

...

DEVICE=eth1:192

IPADDR=192.168.0.1 NETMASK=255.255.0.0

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.

That netmask says the interface handles the range from 192.168.0.0-192.168.255.255. Maybe you meant 255.255.255.0?
