I am using RUT240 with Movistar with Static IP and Public IP.
I have created Port Forwarding and enabled remote management.
I can perfectly reach my RUT240 from outside and see my specific port opened using portchecker.
However, my device reports NAT Type to be Symmetrical, I need to have Full Cone.
So any device on network should be able to talk to my port on the device without my device first talking to that external device.
How can I change NAT type to Full Cone?
