I _think_ you should be able to do it w/ a dynamic address, but it
will need some fiddling. I have half of the solution in mind, but you'll
need to play with it some (I've not set up NAT yet).

The /etc/ppp/ip-up script gets called after the IP address gets set.
It's purpose is to handle routing options more complicated than what
"defaultroute" would cover. ip-up gets fed the local and remote IP
addresses, so it should be easy to re-write the NAT rules to use the
dynamic address.

/etc/ppp/ip-down gets called when things are coming down. Use it to
turn of the NAT rules.

Take care,

Bill
