Centos 7 firewall

July 5, 2016

Just a quick note, I had to open up a hole in the firewall on the server itself (even though I had my router stuff all set right already) by doing:

<i>sudo firewall-cmd --permanent --zone=public --add-port=80/tcp
sudo firewall-cmd --reload
</i>

Worked great. I guess having a firewall on the server itself is good too. Instead of just relying on the one on the outer edge of the network.
