airport extreme (white teardrop) hooked up to dsl modem, two airport expresses as wds...
You have a couple of options...part of the instructions are the same, so do either (1) or (2) and then do the rest of it.
Either way, first go to: Airport admin utility -> your base station -> network. You should have the distribute IP addresses box checked, and also the "share a single IP..." one. Under that, it should say "Use 10.0.1.1 addressing" or "Use 192.168.1.1" addressing or something like that. Make a note of which one you have selected. Now go to the Internet tab. Under the configure TCP/IP stuff, note the number in the IP address box. Now go to:
1) You can put the Mac in the DMZ. This means that the AEBS will not provide any sort of firewall service to it, and every port that you open on the Mac's software firewall will be accessible over the internet. To do this, you run the airport admin utility, open up the base station, go to Airport -> Basestation Options -> select enable default host at... and put a large number in the box (201 is a good choice). Make a note of the whole IP address it makes (the number you enter is the last piece, so it will be 10.0.1.201 or 192.168.1.201 or something like that).
2) Or, you can just open specific ports. In the admin utility -> your basestation -> port mapping tab -> click add, enter in that port number (it was 5010, sorry, not 5050) in both the public and the private ports. Make a note of the whole IP address listed under private address.
Now, go to system prefs -> network -> airport -> tcp/ip. Change the following:
Configure IPv4: Manually
IP Address: Whatever full IP address I asked you to note in (1) or (2) -- the address like 10.0.1.201 or 192.168.1.201.
Subnet Mask: 255.255.255.0, or if there's something else there already, leave it alone.
Router: Should already be filled in, probably 10.0.1.1 or 192.168.1.1
DNS Servers: Put in the same thing that's listed under router.
Click Apply Now.
Now, remember up above there was the IP address from the Internet tab of the Airport configuration utility? The one that was NOT like 10.0.1... or 192.168.1....? Now, you should just be able to put that IP address into telekinesis in place of your intranet IP address, and it should work from outside the local network.
