SmartLink and Apple routers (Airport, Time Capsule, etc)

David Decoons, wo2x

I just helped a gentleman running an Apple Time Capsule router (same as Airport Extreme with the built in backup drive).

We found out that the Airport routers do not support uPNP. We needed to use manual port forwarding. Here is a pdf which describes how to add port forwarding to the Apple router.
https://www.rainmachine.com/support/portforwarding/Port-Forwarding-Apple-AirPortExtreme-Router-for-HTTPS.pdf

You only need to add one port forwarding rule to the Apple Airport (or Time Capsule) router.

On page 4 of the PDF it shows how to add the port forwarding.. Here are the setting you need to enter.

Description: ​SmartLink
Public UDP Ports: ​ 22000  
Public TCP Ports: ​ 21000   
Private IP Address: ​ <enter the IP  address of the radio>  
Private UDP Port(s): ​ 4993   
Private TCP Port(s): ​ 4994

Click ​ Save​  button> The router will reboot.

Next go into SmartLink Setup and expand Network Settings. Click Manual and enter the following settings 



Click Save then click the test button. You should get a green indicator and if you hover over it (SmartSDR) or click it (Maestro) the bottom section UDP and TCP should show pass.

Why the choice of ports 22000, and 21000 on the WAN side?

On my Time Capsule,  I port forwarded WAN side TCP 4994 and WAN side UDP 4993, to the LAN side TCP 4994, and UDP 4993 ports. The SmartLink Test Came back with a green indicator after I rebooted the Time Capsule.

Should I change my WAN side port assignments?

no, you can leave them as-is. Just what we used.

Thanks for the quick reply! I had no particular reason to setup the 1 to 1 pairings I used, and thought I might have overlooked something important.

I think you also need to enable NAT-PMP also.....

David Decoons, wo2x

It was already enabled. Check the pdf article I lonked to in the above posting. Page 4 I believe. Dave

You might want to do a DHCP reservation too.

That I dd early on, setting static address for a number different devices.

Dave - Thanks for posting this, it instantly enabled smartlink for me on my apple airport extreme. I was starting to think it was going to be very complicated but this worked perfectly and was super easy to follow. Thanks again!!!!!

Dave. I have an Apple Airport Time Capsule router. It's so old it really should be replaced but that's another discussion. Thanks for posting this very helpful discussion.
Got it working!!
