Re: Public WiFi Access Authentication

Dear Michelle.

Why don't using a vpn path between your desktop und auth or your
main-router?

Client----------Wireless-Router------VPN-Router-----Main Router
| |
| |
+-------------VPN-Channel----------+

The vpn connection between client and the vpn router could be stablished
with different
authentications methods, e.g. preshared key on the client and the router.
The vpn router opens a vpn channel on a port you choose, e.g. 5004. On
the vpn router
you drop other ports and allow only incoming udp traffic on port 5004
from the interface to the wireless router.

In my opinion this scenario meets the most of your requirements. Am evil
client without preshared key
which overcome the wireless protection couldn't use this capture. The
only connection
could be used is a 5004 udp connection which require a preshared key. So
only if a client started
this half of the vpn connection with the correct preshared key, traffic
between client and the lan
is possible.

with kind regards
