I'm preparing to start a mini wisp and expand from there.

At this moment I have a Cisco omnidirectional antenna. I plan to broadcast out around 5 miles. I getting ready to get TV antenna tower probably 50 foot.

My question is. what will i need on the customer end so that they connect to my network but are actually on their own network. I'm thinking something like a DSL modem type thing only for wireless. see i plan to broadcast a 10.x.x.x address and they will need a device to give them a 192.168.x.x address. My reason being is that i don't really want the customers to be able to browse network neighborhood and see other peoples files or printers.

About my connection.
I have DSL. I already talked to the owner of my ISP and they do not have a restriction on reselling the service as he is also a CLEC.
