firewallhttpiiswindows-server-2008
I'm having an issue with my Windows Server 2008. I can successfuly connect to it with FTP(port 21), remote desktop(whatever the port number is), https but not with simple http or port 80, from the outside of my LAN.
Is there some settings I don't know about regarding this special port on the firewall or on IIS7?
For your information, I can connect to port 80 as long as I'm on the same LAN, but as soon as the request come from the outside, I get nothing…
Please help
Thank you
By default Windows 2008 does not respond to pings. To enable:
Administrative Tools
Windows Firewall with Advanced Security
Inbound Rules
File and Printer Sharing (Echo Request - ICMPv4-IN)
Enable Rule
You should now be able to ping your server from the LAN.
Try the following:
netsh routing ip nat add portmapping external tcp 0.0.0.0 5555 192.168.0.2 3389
This rule shall forward any incoming connection to port 5555 from outside to your specific LAN IP/port. Here external is the name of the external network interface.
Don't forget to have proper firewall rules that will allow traffic related to port 5555 to pass in both directions on the external NIC. You need to allow incoming traffic to port 5555 and outgoing traffic related to these connections.
I've never used the built-in Windows firewall, but I strongly suggest you to have a look at wipfw. It is smart enough to implement connection tracking.

As mentioned in comments, if you are using an ISP's residential plan, there's a good chance they're blocking port 80. Try using a nonstandard, or even just 8080, and see if you can get to it from an external source.
