Scope/Description

• This article will cover managing Firewall in Houston UI

Prerequisites

• Access to Houston UI
• Firewalld installed and configured

Steps

• In the networking tab, we can see the firewall is currently enabled. We can turn it off completely by clicking the button next to it.

• Next, we can select the Edit rules and zones button to configure rules for our firewall.
• We can select Add services to add a new rule.

• Here we can select from some common services, or add a custom port instead. Here I’ve selected the samba-client service.

• Here we can see the samba-client service has been added to our firewall.

Verification

• Verify the firewall rules have been added via the UI, or by running “firewall-cmd –list-all” in the terminal.

root@ubuntu-45d:~# firewall-cmd --list-all

Troubleshooting

• Ensure that firewalld has been installed and configured correctly.
