I have installed a fresh Apache with a fresh Ubuntu server. I did not make any changes to my server yet. The default Apache website is visible from other PCs inside the private network.

The ports 80 and 22 are forwarded properly to the server, and I have setup a fixed IP DHCP 192.168.10.116 from my router.

SSH is accessible from public or private network. But the website is only accessible from the private network. I would like to make the website available to the world.

Note that I have tried this setup with a Windows PC + XAMMP, from which the default Apache webpage had been visible from a public IP.

Below are some details:

    You might want to check with your ISP if they block port 80.

  • @Terrance The ports are unblocked and from windows10+xammp the website was available through port 80. But I am so confused, why its not working in ubuntu+apache2.

    Change Listen 0.0.0.0:80 to simply Listen 80 and report back.

    @Terrance >> You might want to check with your ISP if they block port 80. You are right I check with the other port such 8017 its works fine except 80. Contacted with the ISP to unblock it. Thank you again.

    @Terrance I am scared to say that my the port forwarding rules was incorrect with the Mikrotik(except the 8017 port), after correct it the website is visible to the world. Thank you all!
