IIS not listening over external network, all other traffic working

  • 772

I have a very odd situation, I have a server (let's call it X) running 2008 R2 with two NIC's in it, one is connected to the work domain and has a subnet of 192.168.10.0/24 the other is connected to a ADSL connection and has a subnet of 192.168.1.0/24. The server has IIS installed.

On the ADSL connection I have setup a dynamic dns and port forwarding to allow external HTTP, HTTPS, FTP and RDP connections. FTP and RDP are working fine however neither HTTP or HTTPS are working at all.

I can browse the websites by going to localhost on the machine, the HTTP and HTTPS ports appear as "Filtered" when I try to scan them using PortQueryUI and browsers respond with a "Server took too long to load or was not responding" error.

This was working fine just a few days ago, Windows firewall is disabled I don't have any software firewall on it. And I'm really lost.

Any help would be great.

    Can you try assigning the external IP to IIS and then try accessing the Web site using http://ip_address. Let's see if that works. If that fails, port 80 is blocked on that ip. http://localhost will always. Try netstat -ano and check if you are actually getting connected on port 80 to your external ip.
