Sharing wireless internet to ethernet?

I am trying to share my MacBook's wireless internet connection to the built in ethernet port, but am having a few troubles. I go into sharing options and select "share your connection from: AirPort to computers using: Ethernet". I tick the box next to internet sharing and I get the warning prompt and then click start. At this point I lose all internet connections from AirPort, and the only way I can access the internet again is to untick the box next to internet sharing?? Anyone know what I'm doing wrong? Any help is appreciated!

Cheers

and what does it say ?

Tex

It says it "may affect the network settings of other computers and disrupt the network", which obviously it is doing, but I don't have a clue how to fix it/make it work.

Weird. I will try myself when I'm at home and tell you the result.

Valmorph - check these out - Take Control Catalog - might be the easiest way to set up your network.
