I intend to set up a small Wireless Internet Provider (for about 30 people). I was thinking of using a sort of VPN for authentication. Would this work:
- Server with 2 network cards. One of them connected to the Internet link, the other to an access point that's in bridge mode. Maybe some security in the AP in the form of MAC address-locking.
- VPN (PPTPD) on the server.
On the client:
- AP set to AP client mode capable of authenticating through PPTP.
I think this would provide me with user/pass authentication (which is something I want), and some security. If someone want's to hack it, at least they'd have to bypass the MAC and PPTP security, which is better than nothing.
Or am I totally wrong?
