    Hi. I got my Mac a few weeks ago, and I'm finally settling in. I need to figure out how to use it as a simple Wi-Fi adapter for my Xbox 360.

    I have forwarded ports in my router for the Xbox. Back in Windows, I could simply bridge connections and everything would work right. However, in OS X, when I turn on internet sharing, it puts my Xbox into a different subnet, causing my NAT type to turn to moderate.

    Normally, the correct subnet is 192.168.3.*. (I would like it to be 192.168.0, but my ISP has no idea what they're doing, and they screwed it all up.) When I bridged my Xbox with Windows, it just acted as a Wi-Fi adapter, but in Mac, it acts as a router.

    When I share my Wi-Fi connection with my Xbox, it puts the Xbox in 192.168.2.*. Is there any way I can make it so my Mac just acts as an adapter instead of a router? Can I turn DCHP off or something like that?

    My network setup is like this (sorry for the bad layout): BEC Router/Modem combo (from ISP, DCHP to ----> NETGEAR Router (DCHP turned off, just acts as a switch, adding more ports to the BEC. I use it as a Wi-Fi access point, because the BEC is only wired) ---(Wi-Fi)--> MacBook Pro --(Connection Sharing)--> (normally Get the pun, anyone?): Xbox.

    Just to review, I need to make my Xbox in 192.168.3.*, so that it gets the correct ports forwarded to it. If that's not possible, it would be okay for me just to forward the ports through my Mac, (Router --> Mac --> Xbox), but I would like it just to be (Router --> Xbox, with the Xbox going through Macs Wi-Fi)

    I hope I didn't over-complicate things. Help would be much appreciated, thanks!

    P.S. I'm very tech-savvy, I'm just relatively new to Macs, so you can go full blast :p. I'm hopefully going to start developing iOS apps soon.
