How to autmatically remove/add IP-adress at startup.

[skypher]

Hello.

I have installed ZeroShell on an old computer and has 3 NICs in it. I want to use ZeroShell as a router at work, where I can’t use more than one IP-adress, and I haven’t got access to any switches or hubs.

So my setup is like this:

ETH00 = WAN connection (dynamic IP-adress)
ETH01 = Computer 1
ETH02 = Computer 2

Now, I’ve created this as a sort of experiment to see how much I remember from school about routing and networking.

I’ve managed to set everything up and working, but there’s 1 thing that’s left to do to make it maintenance free, and this is where my problem is.

On the ZeroShell web configuration page, SETUP->NETWORK, under ETH00

There is an entry with ip: 192.168.0.75 255.255.255.0
As long as that line is there everything works as I want it to BUT, when I start the router, Internet doesn’t work on the client computers. I have to remove this IP and add it again and it works.

What I want to know, is what I can put in the startup script to remove / add this automatically so I don’t have to do this every time someone starts the computer?

I’ve tried to type something along the lines of:
ifconfig ETH00:0 192.168.0.75 netmask 255.255.255.0
-OR-
route add 192.168.0.75

But that doesn’t seem to work, or maybe I’m doing it wrong.
