-9. The Fedora repos have a ZoneMinder package available, but it does not
-   support ffmpeg or libvlc, which many modern IP cameras require. Most users
-   will want to prevent the ZoneMinder package in the Fedora repos from
-   overwriting the ZoneMinder package in zmrepo, during a future dnf update. To
-   prevent that from happening you must edit /etc/yum.repos.d/fedora.repo
-   and /etc/yum.repos.d/fedora-updates.repo. Add the line "exclude=zoneminder*"
-   without the quotes under the [fedora] and [fedora-updates] blocks,
-   respectively.
+9. Optionally configure the firewall
+
+   All Redhat distros ship with the firewall enabled. That means you will not
+   be able to access the ZoneMinder web console from a remote machine until
+   changes are made to the firewall.
+
+   What follows are a set of minimal commands to allow remote access to the
+   ZoneMinder web console and also allow ZoneMinder's ONVIF discovery to
+   work. The following commands do not put any restrictions on which remote
+   machine(s) have access to the listed ports or services.
+
+     sudo firewall-cmd --permanent --zone=public --add-service=http
+     sudo firewall-cmd --permanent --zone=public --add-service=https
+     sudo firewall-cmd --permanent --zone=public --add-port=3702/udp
+     sudo firewall-cmd --reload
+
+   Additional changes to the firewall may be required, depending on your
+   security requirements and how you use the system. It is up to you to verify
+   these commands are sufficient.
+
+10. Access the ZoneMinder web console
+
+   You may now access the ZoneMinder web console from your web browser using
+   an appropriate url. Here are some examples:
+
+     http://localhost/zm (works from the local machine only)
+     http://{machine name}/zm (works only if dns is configured for your network)
+     http://{ip address}/zm
