Why are you installing a firewall on a web server *at all*?

The only thing you need to secure is your ssh access, and that's
usually done in the /etc/ssh/sshd_config file, either by setting
up key access only, or by restricting the source IPs who can connect.

The web service is supposed to be open to the whole world.  That's
why it's called the World Wide Web.

Unless this machine is more than just a web server...?
