How to open access from outside to the local server?

Question

Network routing

Good afternoon!
For the convenience of development, I assembled a home server for myself.
Installed as a system CentOS7
Also installed brainycp to manage sites.
Bought a dedicated IP from an ISP.
I registered port forwarding on the router https://i.imgur.com/Yide0Bo.png
Everything is fine here, everything works.
I decided to bind the domain to the server so that I could access sites from the outside.
I registered my IP at the domain itself.
If I access the domain from all PCs in the network, then all the rules work. Same with a phone that is connected via wifi.
But if you connect from outside
If you look at the service https://myopenports.com/scanner , then all my ports are closedhttps://i.imgur.com/TZm8qcc.png
I started to deal with this issue and found how to open them in iptables https://i.imgur.com/M8AIJKU.png Everything seems to have entered the rules.
If you look at the status https://i.imgur.com/grwN5bR.png , then it is present
. Also, if you look through brainycp, there are also https://i.imgur.com/lWzuViy.png
But they are still closed.
How else can you try to open them?

Answer 1

Contact the provider, the ports may be closed on his part.
