IIS server not accessible outside of LAN

Posted on


I’ve started up multiple computers and run servers trough IIS multiple times. I had no problem setting up servers on Windows 7, 8 Developer, 8 Consumer, but now that I have Windows 8 Pro, I can’t seem to get it to work.

My website/server is reachable on the local computer trough my domain name. It’s also reachable on my phone on the same network. But when I put my phone on 3G, or if a friend (of a different household) tries to connect; there is no response. It just waits until it times out.

For more details about “what happens”:
If I open my website on my local computer, it shows up, no problem. If I open the webpage on any other computer on the same router, it shows up, no problem. If I tries to open it in another household on a different router, it tires to load but nothing happens, it’s a white page util it’s timed out.

I’m using the external IP-address, which I found at What’s my IP.org
I’ve looked trough multiple pages trying to find the problem.
I’m letting IIS trough the firewall, even disabled the firewall.
IIS, Network Service, Anonyms Login has permission to read and run the root folder (inetpub)
Should not be any conflict with server-names; new name each time.
I have never before changed anything in the router to get it to work before. And there’s no settings on it either, just a wireless restart option.

I’m running:
• Windows 8 Pro – Swedish
• IIS 8 (8.0.9200.16384)
• Windows Firewall
• Telia router/modem


Take a look at your router, you must forward your 80 port to your LAN server IP address.
