Model: Archer C7

Hardware Version: V2

Firmware Version: 3.15.3 Build 180305 Rel.51282n

Hello Guys,

I'm having a problem with a device that needs a UDP timeout of min 180 sec.
I cannot find the UDP timeout option somewhere, so i suppose its not available.
What is the standard setting for thios udp timeout?

Because all the ports are forwarded, and it's still not working.
IF i test this with my own laptop and listen to the ports, i can see online that both TCP and UDP 53 and 8883 are open.
So it must be the udp timeout that is causing this problem
https://support.chamberlaingroup.com/s/article/Recommended-router-settings-for-the-MyQ-Wi-Fi-products-1484145723404

I did test this straight behind my modem with a public ip on the device without any port forwarding and it works.
It stops working when i put the device behind my Archer.

Regards,
Thomas

@Thomasvd

Hello Thomas,

Theoretically, it is not caused by the UDP timeout; we can do some troubleshooting first to locate this issue and try to fix it.

Have you enabled port forwarding for some specific device but no avail?

What is the current internet IP address of Archer C7?

In the same network, please test whether you can access it with this device's IP address and port number; meanwhile, you can use the WAN IP plus port number to test.

Besides, please use telnet to test:

1. in the same network, please go to run—cmd—telnet lan ip port number

2. in external network, please run—cmd—telnet wan ip port number

Note: Please show us the pictures of the test results.

Good day.
