This is true. The next problem is, which default gateway the customer should use. But
this is easy:
Assume the first PM3 has the address x.x.x.x and the second y.y.y.y
Just do a "set reported x.x.x.x" on the second PM3. Now both pretend to have the same
address. All customers can set x.x.x.x as default gateway on their dialup routers.

This is easy as well, but requires dynamic routing (it could be done static as well, but
I wouldn´t recommend it):
The Cisco just RIP-listens on Ethernet0. Both PM3s RIP-broadcast on ether0. The routing
entry for the customers must be entered in the RADIUS entry (Framed-Route = ...).
The above works for us perfectly with three different NAS...
Please note that one of the drawbacks of RIP is the 30 secs announcement interval. If you
want, use OSPF instead!
