Macbook Pro not connecting to Xbox/PS3 - ethernet

Hi all,


My Macbook Pro with Lion isn't connecting to my PS3 or Xbox via ethernet. I want to be able to stream files and share my WiFi connection. I've enabled the appropriate sharing settings.

When hooked to my PS3, when I do a 'test' connection thing the ethernet connection on my Mac displays the ethernet as 'disconnected' and then the PS3 can't assign an IP. On the Xbox, it doesn't seem to disconnect the ethernet, but it always fails during a test.

I know it isn't my consoles as my friend connected his PC to them okay.

I know it should be just plug and play, which is why I'm a bit confused. My Mac is connected to a weird WiFi connection (the university's - 'enterprise', or something) but I don't see why that would make a difference in just making a simple connection.

Any advice, suggestions, anything?

System Preferences - Sharing - Internet Sharing

Done all that- no luck. At the moment, I'm just trying to get the two machines Mac - Ps3/Xbox and they just don't connect. The Mac and PS3 ping using Network Utility, but it won't connect.

Try this:

How do you connect a PS3 to the internet through a macbook pro MBP has wireless i connected the PS3 to the MBP with an ethernet chord what do i do now subnetmask router etc. thanks

reverse steps 3 & 4 since you're connecting via Airport and want to share via ethernet
