ports 80 and 8080 will be bound to your web traffic, both are standards for HTTP. What are you testing on?

Testing communication over the VPN tunnel. <br />
I can see the server is listening on port 80.<br />
TCP &nbsp; &nbsp;0.0.0.0:80 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 0.0.0.0:0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;LISTENING &nbsp; &nbsp; &nbsp; 4<br />
<br />
However cannot test if accessible over the VPN.

PID 4 is &quot;system&quot; and that's pretty much standard config. It's not the browser that's listening on the port; what does the machine you're interrogating do? Web server possibly?

For some reason doesn't work for port 80 and 8080<br />
C:\&gt;iperf -s -p 80<br />
bind failed: Permission denied.<br />
<br />
Other ports like 443 works. &nbsp;<br />
Is it because something is using port 80 already and iperf cannot bind it?

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.

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.
