I set up a web server on my Windows 7 computer and want to open port 80 so outside computer could visit my web server.

At first, I thought it's the firewall blocking the port, so I open a new rule on Windows firewall to allow the connection on port 80. But it does not work.

Then I turn off the whole firewall, it still does not work.

I just don't know what to do now, Does anyone have any suggestion?

Thanks a

Does your server have a public IP? If not you have to set up port forwarding –  Simon Apr 10 '13 at 6:07
    
Thanks. It's for network inside a router, problem solved. Thanks anyway –  Jiechao Li Apr 10 '13 at 16:20

Skype locks the port 80 by default. Change its settings to use another one.

If you can open the port and your server is working at localhost but nobody outside can access it, its probably your ISP imposing limitations. Some ISPs won't allow regular home users to open certain service ports like 21 (FTP), 22 (SSH), 25 (SMTP), 53 (DNS), 80 (HTTP), 443 (HTTPS) etc.

Thanks. I checked again and finds out that another firewall software blocked port 80. I add a rule to it and it works, thanks anyway –  Jiechao Li Apr 10 '13 at 16:20
