Well first I misunderstood that you had alias'd lo0, I thought you had used
ifconfig for tun0. Secondly I was going to say that it sounded like a good idea
to alias lo0 with your hostname but I tried it and it did*not* work with ppp.
As I said before, I ended up with a 'my addr' of 192.168.0.1 and of course the
ppp session failed.

Not sure what to say ???
