Hello Bros;
Now I have ***.dynu.net host with my ip 51.39.*.* its for my apache server in my PC (windows 10)
So
form my same PC in same router
when I ping or visit my hostname ***.dynu.net it's ok and work fine
when I ping or visit my ip 51.39.*.* not work and cmd tell me request timed out

and from other and different router
when I ping or visit my hostname ***.dynu.net or my ip 51.39.*.* its not work and cant arrive to my pc
- I close firewall and enable all roles in my PC but not work
- I make port forward in my router like next
Name WAN Port LAN IP Address LAN Port Protocol
apache 8080 192.168.1.103 8080 TCP
in local network is work fine but not work from internet
please I spent one week before ask but I can't run it online and can't access from internet to my server

What result do you get if you do a port check on 8080 on your IP address? If the result is fail, you should look into firewall or port forwardng settings.
