Basically, is it possible to NAT my private internal network to a dynamic pool of external (but also private) addresses?
In more detail, here is my situation. My private network currently sits behind the private network of a larger entity. We have a 192.168.X.X network range and internal traffic is on eth0 and external traffic runs over eth1.
Because of a connection change between us and the entity we sit behind, we have to move to a 10 address network. It is going to take a lot of time and work to change the addresses on everything, so in the meantime we want to NAT our internal private 192 network to a pool of "external" private 10 addresses.
I can see how to masquerade everything to a single address, but how can I setup a dynamic address pool so that each local device making an external connection gets it's own 10 address from the pool?
