I did the port forwarding
From the web console I select ADVANCE → ADMIN PANEL; i logged with admin parameters then I select Networks->Firewall, and finally I pressed onPort Forwards` and i set the router like in the picture
( As in the post https://forum.gl-inet.com/t/gl-mt300n-v2-port-forwarding-and-ssh/3842/3 .)
Now I still miss the packets blockages ho do I set the firewall rules? Thanks
