    Please stop flooding. :)
    RTFM -> man ifconfig ; man route

    you CAN'T change your NIC's ip whithough deleteing your default route.
    why's that?
    well... route add default 192.168.0.1
    when you add default gw it must be reachable on your network.
    when you change ip, you have to add ne w route because you;ve changed
    network.
    aka you can patch ifconfig command to check if you change ip address to
    other form your network(192.168.0.0 for example) and don't delete
    default route... dunno ... I think ifconfig deletes it. not pretty sure.

    a simple desicion will be a bash script:
    ---- ./chaddr.sh rl0 192.168.0.50 255.255.255.0 192.168.0.1
    ###############i-face ip nmask gw

    #!/bin/sh
    /sbin/ifconfig $0 $1 $3
    /sbin/route add default 1$4
