I have an Amazon EC2 Windows Server 2012 instance set up with IIS 8.5 and I'm trying to setup multiple sites, each with a unique port binding. The problem comes when trying to access these sites from outside the instance.
- I have tried many different ports, including: 80, 81, 8080, 2468, 10000, 10001, 10002
- I have configured physical path authentication/authorization for the sites/app pools
- I have configured Windows Firewall to allow inbound access on the necessary ports
- I have configured the EC2 security groups to allow inbound access on the necessary ports
The only ports I have found to work are 80 and 10000. (Likely irrelevant, but the FTP site is working correctly.)
- sites are accessible via localhost on the instance
- When I use an online port checker tool, the ports show as open
- "netstat -an" shows the ports as LISTENING
- browsers (Chrome, FF, IE) show connection timed out when attempting to browse to one of these sites
- cannot telnet into any port except 80 (not even 10000 which works in browser)
- disabling Windows firewall on any/all profiles doesn't help
- allowing all inbound traffic in EC2 security group doesn't help
I don't think this should be a complicated problem, but I've spent a long time trying to figure it out and find answers online, and I haven't come across anything relevant. Most of the search results say to open the ports in one firewall or another, which I've done to my knowledge.
Am I missing something? Other troubleshooting ideas? Let me know if I can provide more information. Thanks.
