Okay, I'm struggling a bit here. I'm not all that good with Terminal and sorting out network issues using it but I've managed to scrape by so far.

Without using Internet Sharing (because controlling that via Terminal as per my question here doesn't actually seem to work in Yosemite) how can I share my internet connection from one interface (lets say en0) to another (again, lets say en1)?

I kind of understand that Internet Sharing creates a bridge (usually called bridge100) and then uses bootpd (I think) to establish a DHCP server and NAT to route all traffic from 192.168.2.xxx (which is the bridged network) through to your primary network.

How can I get the same result without using the Sharing pref pane?


Question: Why does George Mcfly employ Biff to wax his car after he had previously tried to rape his wife?
Answer: In the book version, it makes it clear that Biff was, indeed, trying to rape Lorraine. When he sees her in the car after threatening to take the damage to his own car out of Marty's ass, he says (in the book) "Maybe I'll take part of it outta your ass."

The book then goes on to say, after Marty is locked in the Starlighters' car trunk, that Marty was kicking himself, figuratively speaking, for the fact that "if it hadn't been for him, Lorraine would be inside enjoying the dance instead of having to fight to avoid being raped".
