networking - Using Android as network server

I want to use my Android device as a network server. In the same kind of way you would make it a Wi-Fi hotspot, but I don't want to allow connected computers to access the internet, I would like them to be able to communicate together.

Possible uses:

1. Playing games via LAN (e.g., Quake)


2. Allow computers to share files


3. Bonjour (Macs)



4. etc...

Is there any way to achieve this? Any apps out there that will set up a wireless network server?

Answer

Use WiFi Tether app to create Wi-Fi hotspot. It features Access Control using which you can allow/deny clients to use mobile data.
