Even though there was an inbound rule for port 443 already in the firewall (World Wide Web Service (HTTPS traffic in))<br />
I still had to create another inbound 443 rule and then it worked.

On my computer, port 443 is opened for Secure Web Server Access (HTTPS). &nbsp;Telnet does not do 'HTTPS' so maybe that is why.

It was not the protocol that was the issue it was merely the port.<br />

Telnet works fine to just let you know that port 443 is listening.<br />
<br />
I just successfully tried it on Windows 8 and Mac OSX.

I am trying to telnet to my server on port 443.<br />
<br />
I have a utility listening on port 443.<br />
<br />
I have an Inbound windows firewall rule allowing traffic on port 443.<br />
<br />
I also have other inbound firewall rules on other ports.<br />
<br />
I can successfully telnet on my other ports.<br />
<br />
I get no response when I try to telnet on port 443.<br />
<br />
I turn off the windows firewall and then I get a response on port 443.<br />
<br />
Any idea what would be causing windows firewall to block port 443 even though there is a firewall inbound rule allowing it?<br />
<br />
Thanks, Kevin.

Windows firewall issue with port 443

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
