How i can see my domains in my local network

[loverdeveloper]

Hi,
I have a centos7 running Directadmin,
I have some domains like `example.com`,
when I open my domain in my local network, the browser is redirected to my router (192.168.1.1)
I can open my websites from outside of my network and inside the server!
(Websites are not available in wifi or LAN...)
What's going wrong here?

Can you perhaps clarify the role of the modem on your LAN? Is the Wi-Fi and CentOS server on the same LAN? Do you have NAT anywhere in there?

Yes, all my network is connected to one modem (both LAN and wifi),
Yes I'm using NAT in my modem

It sounds like maybe the router function doesn't support NAT loopback, or "hairpinning", or it is not configured.
