Missing router settings

[Mvill]

Good evening,
I have was checking the user manual of the router of the Internet FIber Box. 
I have seen that there are some settings (Port Forwarding, Port-Triggering and DMZ) that are not available in my router setting page.

How can I gain access to those settings?

Thank you in advance for your help.

You have to request an public IPv4 address. Then these settings will show up. 

Please contact the magenta service team.
