I setup a server dedicated to running Web and FTP for our company. I opened up ports 21 and 80 on our router and used a webbased tool to verify the ports are open. I then closed the ports on the router and verified if it would update as closed, which it did. So my settings on the router are correct.
On any local machine, I can type in the local IP of the website and see the default IIS page. However, I can't access it using the public IP. I tried accessing from an outside network, a mobile smartphone, etc. I opened up port 80 and 21 on the server's firewall. Still nothing.
Any idea on what I need to check/configure to get this to work?
