If you need to image a machine and it is not on the 10.2.118.x subnet you will have to change the following file:

• /etc/sysconfig/network

change the gateway to 10.2.117.1 or whichever subnet the machine will be on. The following commands are a useful guide:

cat /etc/sysconfig/network
GATEWAY=10.2.117.1
service network restart
