[SOLVED] Comodo v7 blocking HTTP/S and FTP/S on Windows 8.1 IIS 8.5

Besides opening incoming HTTP ports in the firewall via “Global Rules”, the annoying thing for me to find was also adding an “Application Rule” for “Windows Operating System” on those same ports.

Comodo v7.0.317799.4142

And this guy explains what’s necessary for FTP very nicely…

  • in comodo > global settings > application rule – add 20,21 & 5000-6000 as allowed incoming TCP ports on “Windows Operating System”… you will also hopefully get prompted to allow svchost which is responsible for running the ftpsvc
  • on internet router – forward ports 20,21 and 5000-6000
  • in IIS FTP settings
  • filezilla settings
    • require explicit ftp over tls
