So I have a home network without internet, and permission to use the neighbours wifi. However, not all devices on the LAN have a wifi card, so I would like to share/proxy the wifi network to the wired LAN.
On Mac there is a feature called "internet sharing" that seems to be made for this purpose. I've successfully used it in the past to do the inverse(share ethernet to ad-hoc wifi).
However, it doesn't work out of the box.
If I connect a computer directly to my Mac, it seems to obtain an IP from the bootp on my Mac. Internet on the connected PC doesn't work though.
On the LAN setup, I'm not even sure how this is supposed to work. I only faintly remember than in Windows XP there is this option called something like "this computer connects to the internet via another computer in this network".
The network contains a mix of Mac, Windows 7 and Linux computers. Any advice how to make this work?
