Access blocked by IP address but blocked

Access was also possible from PC with 118.241.174.59 · · ·

Why··

  1. Make sure That is the Public IP by services like this one.
  2. Make sure Firewall is active (orange cloud)

Why can I access???
I don’t understand

・My PC’s IP
118.241.174.59

・server URL
https://okamenavi.gnext.asia/crmotion/

・firewall

・oragen cloud

Try this URL: https://okamenavi.gnext.asia/cdn-cgi/trace

It should show you the IP address it thinks you’re connecting from.

Is it necessary to enter IPv6 and block it?
Is not it good for IPv4?

Also, even if I set a whitelist, is it possible to access when using an
address other than whitelist?

In that case, I think that whitelist has no meaning

So…you’ll have to block the IPv6 address, as that’s what’s showing up in the Trace.

Whitelist is good if:

  1. There’s something you do that constantly trips a firewall rule.
  2. You’ve blocked/challenged an IP address range that would normally apply to you.

Now…what is it you were hoping to accomplish? A whitelist by itself won’t block everybody else.
