The most straightforward solution would be to call
your ISP and tell them to change the PPP IP to the
IP you want from your network. For example:
10.0.0.1/24 on your lan0
and 10.0.0.1 on the ppp interface.

Other than that, perhaps jail to fool the system
to use another address or some form of NAT.

There is no such thing as in the Linux example, as far
as I know.
