What should i allow trough firewall from programs or services to fix this problem? November 28, 2017 at 5:15 pm #2878 MikhailModerator Hi, What Windows version do you use? You should open incoming connections on TCP port 80. To check, just open http://yourIP/ from another PC. You should see IIS welcome page.
