HTTP.sys Does not work from the global network

[Jose Nilton Pace]

Hi, i try to help you with http.sys.
1st - put http.sys to run on port 80 and if you have https, put on port 443 too.
2nd - Configure your router:
  On the router settings:
  external port: 21401    //or any other port you want
  Internal IP : 192.168.0.103
  Internal port: 80
  Protokol : TCP
3rd - ServerController -> URLBase: /MyBase/

Now you can remove your firewall settings. Not needed if you use port 80 or/and 443.

This may not be the same issue but just in case - I had to add an inbound rule in Windows Firewall for httpsys to work like so:

You're right ! This is exactly it ! I created a rule for the firewall and everything worked. I created the rule not for the program name, but for the port number.
