I have some tasks to solve and I will be thankful if you give me some ideas.
The task is the following:
I want to make a pay zone and free zone. For example - in hotel the pay zone will be the rooms, and the lobby, reception and restaurant will be in the free zone. My idea is to configurate two interfaces - the hotspot (the pay zone) in one interface and the free zone to be in different interface.

If someone has idea about it, please share your thoughts.

Ou can make like this with a 450, for example, yes.

One interface to adsl, one with hotspot, another with diferent ip range and a masquerade for the last interface and enjoy ; )
