Need Help With SmartLink on a ATT Fiber Router

Hi,

There was a previous thread last year about this, but I was not able to post images at that time. Looks like I can do that now so will post some pics with the description of each step.

1) Connect to your router (mine is 192.168.1.254) and create a custom service for each forward (4993-UDP, 4994-TCP) in the Firewall -> Nat/Gaming settings panel. 

2) Then create an Application Hosting Entry for each service that points to your radio (the serial number will be in menu assuming it's connected to your local network).

3) These two entries are all that is needed. I use the default port numbers (-1) in the SmartSDR client to keep things simple.

Good luck! 73

In case someone arrives here with my situation …

I have an eero wireless router connected to my AT&T fiber modem. I am not using the wireless or wired network provided by the fiber modem, other than wiring the eero to it.

For my Flex 6400M, I had to do all of the above (thanks Phil!), with my laptop wired directly to the fiber modem. I then had to do the same thing on the wireless router. If you have another router connected to your fiber modem like me, then you will need to look up in your documentation how to open up the TCP and UDP ports in the router's firewall.

On the eero, I used the phone app, going to Settings, Advanced Networking, Reservations & Port Forwarding. There I added a reservation for the Flex radio. If you have an M model, make sure that you're picking the radio and not the front panel. On the initial startup screen for the Flex, there is an Info button that will tell you what their IP address are. After saving the reservation, I used Open a Port twice for 4994 TCP and 4993 UDP.

Back on the Flex radio, I hit Network Settings, which gave the option for Manual Port Forwarding. I selected that and entered 4994 for TCP and 4993 for UDP.

I then hit Test, and got the glorious green circle!

Hope this helps.
