Problems with SmartLink using ATT Router without PnP

tomblasco Member ✭✭

I have recently purchased a 6600M. I tried to set up Smartlink on a mesh (EERO pro) wifi. That didn't work. So I spent a lot of time attaching my computer and 6600M to the LAN by ethernet.

This setup still did not automatically establish network settings because my AT&T router does not allow PnP!

Now I am in the 'port forwarding' mess with lots of issues related to individual ISP routers variations, with no Flex support available. I have two questions:

Do I set up port forwarding for just the radio's IP address ( What about the front panel with an IP address of

What address numbers do I use for the external TCP/UDP port forwarding?

Thank you!

    Hi Tom, Flex support is available. I would submit a help desk ticket if you have not already done so.

    Alan, here, across the lake from you in Michigan.

    For your port forward questions;

    Forward two ports, each, to your Flex Radio IP address. No need to do anything with the "M" front panel IP address.

    UDP port 4993 to your Flex IP

    TCP port 4994 to your Flex IP.

    In the Smart Link setup, be sure these same port are entered, as a manual setup.

    I want to add a bit on this.

    If you don't know anything about port forwarding, please open a support ticket. Now is not the time to guess about it. :) If you have to to hard code ports then you also really need to do a TCP/IP reservation on the radio so that its IP address never changes.

    We don't recommend using the same port of both sides of the firewall. While there is nothing wrong with it, it is a bit better to use another port way up, like 22000 and 23000.
