[3.5.54375.427] Allow incoming www connections?

Hello

I don’t know how to configure Comodo to allow incoming www connections from the Net. I clicked on Firewall > Advanced > Network Security Policy > Global Rules. There, I Added a rule:

Action = Allow
Protocol = TCP
Direction = In
Destination Port = SinglePort 80

Still, users can’t connect. Is there something else I need to do?

Thank you.
