Flint GL-AX1800 - 2 problems + upgrade on version 4.2.0 snapshot impossible

Hi K3rn3l_Ku5h , thanks for your time.

uboot2.0 version:22.07.10

To clarify - this morning I did the whole process again - uboot upgrade to uboot-gl-ax1800-20220711-md5-9890c67c3dafa5aec172f3a31583f9a7.bin
Then upgrade to openwrt-ax1800-4.2.0-0121-1674260559.tar

Still is here problem with WireGuard

  1. I turn on the WG server
  2. I will add a profile
  3. I scan the QR configuration
  4. the client does not connect, the connection does not work

Where and what do I need to set?
In Luci? Because there is no other option in the Admin panel.
And when in Luci - what should I change there?
Something with routing? Because I’m not good at it.
Where can I find instructions for standard WG operation?

In Luci:

interfaces:

firewall

firewall rules


Here I tried wgserver_allow from wan to lan - same result.

P.S: Resolution: Need open specific port on Firewall - Open ports on router. In my case 51820. I am an idiot.

Thank you all for your efforts and help.
