Is there a way to utilize an Airport Extreme in order to VPN in? Not using MobileMe
Best Answer
The Airport Extreme is just a router - it doesn't provide any support as a VPN endpoint itself.
You can use a computer with the server side of the VPN connection (eg. OpenVPN, VPN Access in Mac OS X Server, etc.) to truly VPN in. You will need to tell the Airport Extreme to forward the necessary ports to that computer.
Of note Mobile Me's Back to My Mac service connects to directly to your Mac and has nothing to do with an Airport Extreme, the reason Apple recommends it is that they "know" that an Airport Extreme plays nice with UPnP and handling IPv6 traffic.
It is quite possible that there is a problem with autonegotiation - that's definitely one of the things I would look at, unfortunately I don't know enough about the airport to know if it's capable of that.
