change IP and default route.

["Dr. David Kirkby" <drkirkby@medphys.ucl.ac.uk>]

Hi,
   I installed a system on a company network with a fixed IP 
(213.78.42.115), but recently bought a small router. The PC will now 
have to use the router as the default route, and I will make the IP 
private.

The following commands do what I want

# ifconfig eth0 192.168.123.1 netname 255.255.255.0 # set my IP to 
192.168.123.1
# route add default gw 192.168.123.254

But how do I set this to happen automatically?  I changed the IP in 
/etc/hosts, and had an attempt at changing /etc/gateways, but clearly 
not successfully, as the routing does work after a reboot - I need to 
type these commands again.
