Once upon a time Allen V. Vartorella shaped the electrons to say...

Side note: I've used the first/last segments all the time, never had a
problem.

This questions is't quite cut and dry, there are differences.

Is this a hardwired connection? If so, you make the entry on the PM itself:

add netmask x.x.x.x 255.255.255.240

Where x.x.x.x is the network low end IP of the segment.

And then:
add route x.x.x.x y.y.y.y 1

Where y.y.y.y is the IP of the far end of the SLIP/PPP connection.

The subnet x.x.x.x is then routed via y.y.y.y

If this is a dialup connection, modify the Radius entry for the user:

Framed-Address = y.y.y.y
Framed-Netmask = 255.255.255.240
Framed-Route = "x.x.x.x y.y.y.y 1"

This way the user can connect to different PMs.

Note that y.y.y.y is usually an IP out of the x.x.x.x subnet, most users
user the first host IP for this.
