Why i put in this code, still cannot run?

i am using RB450G, and i had reset the device...so it totally don't have any setting on it..

add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=Local <== is this Eth1 port for local?
add address=192.168.1.2/24 network=192.168.1.0 broadcast=192.168.1.255 interface=WAN1 <== is this Eth2 port for my WAN 1?
add address=192.168.2.2/24 network=192.168.2.0 broadcast=192.168.2.255 interface=WAN2 <== is this Eth3 port for my WAN 2?

and do i need to setup dhcp for my Eth1 which is local?

Do you have an interface that is named Local, WAN1, and WAN2? If not then that is a problem. You also don't need to specify the broadcast IP and Network IP manually, that will be calculated by the router internally by specifying the /24 after the IP. By placing them in a console session it should highlight any syntax errors that you are running into for your particular version.

ya.. i have the interface named Local, WAN1 and WAN2, but it seems like not working

Have you tried removing the broadcast and network parts of the command? Have you tried pasting the commands directly to a console or SSH session to see what the syntax errors might be?
