Ipv4 port forwarding on Internet Fiber Box 2

[ProtoBn]

Hi everyone,

 

I need to set up a vpn to access to my server from outside of my network, but in the webgui of the box there is only the ipv6 port forwarding but nothing for ipv4.
Is that normal or maybe I am doing something wrong...
Does someone has a idea on how to get the ipv4 port fowarding on?

 

Kind regards

Your cable internet is probably using a public IPv6 address (and private IPv4) instead of a public IPv4 address.
