VPN and Airport Extreme (802.11n)

I am considering buying this new Airport, but I will need to set up a VPN between it and my work location. Can this device cope with doing that? The old Airport Extreme could not.

If you go to Internet->DHCP in the AirPort Utility
you can tell the AirPort to give a specific IP
address to a specific MAC Address in the DHCP
Reservations section. Set that up and then use the
ip address as the default host. You can determine
your MAC address by running ipconfig /all from cmd in
Windows or "ifconfig -a" from terminal on your mac.
Windows lists it as the "Physical Address" and OS X
shows it as the "ether".

This will effectively give you a static IP without
you having to adjust your network settings.


Thank you. Amazing that you knew this was how to fix it, but it works for me. I'll still call Apple and register my complaint. I am sure each call gets closer to getting a solution from them.

I had problems after installing update 2007-002 on my MBC2D with a d-link router. Tried everything when finally I applied the update a second time from apple web page (not from the updater where it doesn't show up). Then it suddenly just worked. It seems to me that apple may have fixed the update quietly and still gives it the same name. 20007-002.
It may be worth a try.
So happy it finally works....

For what it worth I just received and installed a new AEBS yesterday - zero problems until my wife tried her VPN. No dice...We both use AT&T Global Network Client for VPN connections to work.

6 hours later I tried the latest version of the AT&T client (v6.9) and the problem was solved. Upgrading meant changing the company delivered configuration...tried to avoid that, but no other solution worked.

The "DMZ" style fix also worked, but would not have been acceptable for more than a day or 2.

Is there a way to connect the USB720, or other, broadband modem to the airport base station to broadcast the internet conneection over the area? I have a snow and want to connect my new Verizon broadband to it to get it working for everyone. I don't want to use one computer and share the connection, it doesn't work at all with WOW (red bars all the time 🙂.

Any help would be appreciated.

Thanks,

Karl

Just to refresh on this post and thread, which I originally posted on 21 January: I am trying to set up a VPN between my laptop and my machines at home(work).

I have a LinkSys VPN broadband router at the home end, and would like to set up a secure wireless network at two other locations to connect to the home computers over a VPN, preferably using Airport Extreme Base stations. I am not very technical, and find the Airport a relatively easy device to configure.

My question is very simple, and is still unanswered:

a) Can An Airport be used to do this?
b) How do I do it?

Apologies from myself and the others for hijacking your thread and not answering your question directly.

If I understand you correctly, you want the Airport Extremes to serve as secure ends communicating over the internet, establishing a VPN link betwen eachother, to which you can connect clients to comminucate sceurely.

If so, no, I don't think they can. The Airport Extreme's are not VPN appliances, they are merely wireless and wired routers you connect to a broadband source such as a DSL or Cable modem. Their purpose is to share a single internet connection to one or multiple PC's or Mac's, either by wireless or through ethernet cable.

The way I understand it, VPN connections are from a client, over the internet through an Airport Extreme or other type of router, to a VPN appliance to establish a secure connection into a private network on the other side of the appliance. The router should facilitate the connection by allowing the special ports to be used, but other than that it is just a transport device.

Did that answer your question or am I way off?

From what I've read in this topic and from what other users have been saying is that the old Airport Extreme (802.11g) had the capability to setup VPN passthrough, which currently the new Airport Extreme does not provide. I think that is truly the dilemma most of us are having - can the new AEBS 802.11n handle VPN passthrough? I believe the answer is still no.

According to Apple's specs for this device, it is SUPPOSED TO allow VPN passthrough. There is a bug and they are aware of it...they are taking way too long to get a patch out though as this is critical to many people (like myself).

I had to reinstall my dlink until Apple gets this right.

Unfortunate, my Apple TV arrives tomorrow and I'd love to have the new N router running!

Thanks to all for this thread!

I had the same problem -- couldn't Checkpoint VPN from my Windows laptop through the Airport Extreme N. I tried the "turn off UDP Encapsulation" workaround mentioned above and it worked. Lucky, because unchecking that box was alot easier than the "default host" fix described on this thread.

BTW: To find the "Force UPD Encapsulation" checkbox (so you can uncheck it) on the Checkpoint VPN: click Options on the login screen, select Edit Profile, then select the Advanced tab.
