Complete noob here when it comes to routers and port forwarding. I have a strict NAT and I would like to try and open the ports, but I am really confused with all the buttons after I logged into the router. I've tried multiple tutorials about port forwarding but still keep getting strict NAT. Probably doing something wrong. I also don't know what type of WAN I am using, there are so many options: Fibre, all Ethernet, all ppp, all vlan, all wireless, ether1, ether2, ether3, ether4, wlan1.
TCP: 80, 443, 14000, 14008
These are the ports I have to open up. Please help. Thank you in advance.
