How to join my dedicated server from public IP

Assumptions and things I want to realize:
I want to set up a dedicated server on Unreal Engine 4 and put it on my server (home PC) from outside the local.
A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums (Windows_% 26_Linux)
I checked this site and put it on multiple servers locally, but then I could not connect it from public IP

what I tried:

・What I tried was following my global IP: 7777 and I specified a port number

・I completely cut off the security software included in Windows and made it without a firewall.

・The ports are directly opened up to 7777-7780 by TCP / UDP in the setting of the ONU.

・It may not matter because you are looking at a site for overseas dedicated server but there is no mention of port

opening in detail, but if you check at a site where you can check if it can be opened, you can open the port I was told not to.
(The global IP itself should have been assigned since it was firmly set up when Minecraft Server was set up in the past.)

There may be a small amount of information in the Japanese language and it may be misrecognizable, but as far as I checked out, I could not identify the cause.

and sry with my bad english with google translator

You need forward your private address port over your router NAT (thing that translates private<->public address), you need to do this in router settings, here some site showing guides for various routers:

maybe I have already do that. Screenshot - 115052917d7571e469c2a1945de632cc - Gyazo this is correct?

a little bit continued, terminal show me error message.

this ip is public ip

I resolved!
I joined from Mac OS, and I changed joining OS windows.
I succeeded!
