This is almost certainly wrong. Isn't tun0 getting an IP through
ppp(8) or the like? I guess I could be wrong, since the above address
is in AOL's netblock. Do they have some odd service where you get a
fixed dial-in IP? But my best guess is that you meant to use an
RFC1918, unregistered address; that is not one.

Typo, I assume.

You have not indicated you have ipfirewall(4) (ipfw(8)) up and
running. However, the -nat option with ppp(8) is probably a better
idea.

The gateway of the local machines should be on their local network of
course.

Your NIC on your private network should definately be getting an
address from ifconfig.

You do seem very confused.
