Two levels of security on one Airport Extreme?

sypark - I had the same question some time ago and the best understanding I came away with is NO - you can only have one security protocol on the AEBS at a given time.

Not sure how accurate my understanding is but there it is 🙂

This is correct, but remember that to log onto a computer from a network requires that file sharing is turned on at the target computer, and that the user logging on have a password...

Once you give them access to your network, they have access to your network.

You could put your computers on a different sub-net. To do that you would need to configure things like this:

internet-> [WAN] router_1 [LAN]-> [WAN] router_2 [LAN]

Both routers need to have DHCP enabled.

Allow your visitors to connect to router_1.

Connect your computers to router_2.

This will place your computers on a different subnet and out of reach from the visitors computers.

Everybody will be able to get to the internet.

However, computers on one subnet will not be able to communicate with computers on the other subnet.

That is true and I believe that is what sypark desires.

|-LAN Port Linksys--WAN (circle of dots) AEBS

And... ensure that:

• The Linksys and AEBS have different network names and passwords.
• Using the described configuration, your visitors should connect to the Linksys. This will prevent them from accessing your machines connecting to the AEBS.
