Public wireless access point on a private network
I am trying to figure out how to achieve that. I want a public access point that would allow connection to the internet. Also I want a private access point that would allow connection to the internet plus to the wired network. I would like computers at private network to be able to communicate , but from public restrict any access to private network.
If they didn't share the same internet modem-router that wouldn't be a problem..
Currently I have an Access Point, a ISP modem router and a simple switch.
