Nighthawk RAX40 Port forwarding not saving

[jeroenvo]

Hello,

I need to open ports for my nintendo switch (45000 - 51000) but the router does not want to save the page.

192.168.1.4 is the ip of my switch, the message in the left corner keeps saying "Waiting for 192.168.1.1..."

Does anybody knows how to fix this?

My firmware version V1.0.3.64_1.0.1

[Apocalypto]

I'm on:

Firmware Version

V1.0.3.80_1.0.1

Hardware Version

R1.05

Did everything by the book, asigned reserved IP for my PC, rebooted both router and PC,

doublechecked IP and Ports after reboot.. 

but sadly

*sigh*

specified ports are still closed..
