I have a web server running on IIS Express.
I modified the bindings in my IIS instance to run on PORT:COMPUTERNAME and also added a rule to the firewall to allow inbound requests on that port.
When I navigate to
http://COMPUTERNAME:PORT on a windows laptop over LAN, I get my webpage, however the same thing on my OSX never connects. I've tried
http://IP4ADDRESS:PORT to no avail.
I can ping the ip4 of the server and get a response just fine.
I'm not running on a domain, and both computers are in the same workgroup.
