i cannot ping the 86.124.190.248 not even from the router

I need to connect to make some port forwards in order to access some equipment's from WAN, but because i am unable to understand why i cannot ping the public ip it gives me some headache

Thank you

you're on a CGNAT, without a public IP.

OK, and is there a way to overcome this?

IPv6 perhaps, or something that would allow you to bypass the CGNAT, like tailscale, zerotier etc.

  • asking your ISP if there's a different (businiess?) contract with a public IPv4 address
    • some ISPs might be convinced that you need a public IPv4 address, but that's getting rarer
  • switching ISPs
  • IPv6, as frollic already said
