OS X Internet Sharing As Wireless to Ether Bridge

sanford · 10-11-2006, 04:34 PM

My network looks like this:

Cable modem connected to Linksys BEFSR41 wired router for wired device; Airport basestation (of the "snow" variety) connected to the Linksys router to provide wifi for the wireless devices -- no NAT or DHCP running on the Airport base; just bridging to the Linksys.

I'm using an old Airport-enabled iBook running Panther as a wireless to ethernet bridge to a game console, an Xbox 360, with a wifi adapter. The iBook is connect to the Xbox via ether cable. I'm using Internet Sharing to share with iBook's wifi connection. The rest of my network, including the iBook, is in the 192.168.1.x range, while the Xbox hanging off the iBook is on 192.168.2.x range, router set as 192.168.2.1 (the iBook), all manually assigned. This works fine for connecting to Xbox Live, the Internet game service, but is causing some problems with using a piece of software that lets me share media from my Macs with the Xbox 360.

All I want to do is use the iBook as a wireless to ethernet BRIDGE. No NAT! I want the Linksys wired router to do all the NAT. I assume this would also allow me to set the Xbox to configure IP automatically via DHCP on the Linksys, just like the rest of my network does over Airport bridging to the Linksys router and its DHCP server.

Seems like I should be able to do this, but after some digging, I can't figure out how.

The iBook is actually running Jaguar, if that matters.

I think I know what's going on. It's the same reason I can't get an address via DHCP for the Xbox 360. It's not IP. DHCP uses some other protocol. The DHCP requests coming from the Xbox are getting eaten by the iBook. Is there any way to get it to let those service requests that aren not IP-based get out and on down the network?

I would also like to know how to share the internet via ethernet on an iBook without NAT being on.
