Inbound traffic

Once the minimal set of rules is deployed, any other role installation can add specific rules files in the /etc/nftables folder. For instance, when installing the Jabber server, additional rules are deployed for client to server and server to server connectivity (ports 5222 and ports 5223).

Conversely, when the Jabber de-installation tasks are executed, the same rules are removed, and the firewall is reloaded.
