Exactly that's what I did describe in my message: Configuration
data is set in ppp.conf, no DHCP involved, and the actual IP will
be delivered to the tun0 interface, while fxp0 (in this case)
can be used for involving with NAT (if required). Setting the
nameserver to an _actual_ nameserver (either running named on
the machine, or relying on the ISP's nameservers) is required.
This is the easiest approach to dealing with PPPoE modems (if
they are used as "actual modems" without any additional routing,
DHCP or other functionality).
