If you're running a web-app on port 8080 and don't want external users to see the app, how do you block it in Windows Firewall?

Question

When I'm working on my app in a coffee shop, I want to make sure no one can see the app, which runs on localhost:8080.

How do you configure Windows Firewall to block external connections to 8080 but still allow you to connect to the port on your own machine?

Answer 1

The answers to this question of mine on Stackoverflow.com allow you to set this up, however this is using Apache rather than IIS.

Answer 2

Windows Firewall should be doing that automatically by default unless you explicitly open it. Which perhaps you have for when you're not at the coffee shop, but network profiles (Home/Work or Public) or what you want to use. If you have a rule allowing access to 8080, make sure it's enabled only for Home/Work and not for Public. Assuming that you use Public when connecting to an untrusted access point, which you obviously should.
