Super User is a question and answer site for computer enthusiasts and power users. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I'm very confused. I'm using Comodo Internet Security as a firewall and it is blocking requests from my mobile phone browser to my local webserver. If I disable Comodo firewall it works, and it's pretty obvious Comodo is actually blocking something because of the logs Comodo firewall port forwarding lost here and appreciate any guidance!
