Fritz,
Change the IPADDR to be 192.168.10.? and the NETMASK to be
255.255.255.0.

Subject: RE: iptables or routing problem
Sorry for being ignorant... but how do I limit the subnet of eth1 to
192.168.10.*/24?
here is my current ifcfg-eth1:
BOOTPROTO=none
GATEWAY=192.168.10.240
DEVICE=eth1
MTU=1500
NETMASK=255.255.0.0
BROADCAST=192.168.255.255
IPADDR=192.168.8.232
NETWORK=192.168.0.0
ONBOOT=yes
