set a persistent route

[Guillaume]

Hi everyone,
I completely reconfigure my network settings today, (network @
192.168.1 to 192.168.154) everything work fine but i have to enter the
following route each time the server start

#route add default gw 192.168.154.34 eth0
i add this line in rc.local, but i dont like this. Is there any other
file i have to edit where i have to set my routes (i mean when system
is starting up and net. interface mounted!)

many thanks,
Guillaume
