Can somebody please explain something to me?

What's the difference between using "-o ppp0" and "-o eth0"? Obviously, 
one is using the ppp0 interface while the other is using the eth0 
interface. But in terms of what happens to the packets, what's the diff?

Out of curiosity, I tried both: ppp0 works, while eth0 does not.


Cheers,
Dave
