 The first rule we add is for accessing DynMap :

+So, as the source, we set it to ANY, so : 0.0.0.0/0
+For the port, if you let the default one : 8123
+The protocol is TCP (standard for HTTP)

 Then, we also need to allow the access to our Minecraft server (depend on which version you installed and/or mods to allow either clients to connect to your Java server)

 For all those settings, adapt the destination ports to your needs.
 
 After that, you should have some rules like those one :

 #### First way - Default firewall application : UFW
 
+First, and not mandatory (so you can skip those initials commands), we restrict any inbound connections.
 ```
-To be completed, later... :D
+sudo ufw default allow outgoing
+sudo ufw default deny incoming
+```
+
+Now, we are going to open some ports, first SSH access (in case you change from the default SSH port (22/tcp), adapt the command accordingly), then DynMap (8123/tcp) and the port for the Minecraft server :

+```
+sudo ufw allow ssh
+sudo ufw allow 8123/tcp
+sudo ufw allow 25565/tcp
+sudo ufw allow 19132/udp

+Add any rules you needs, then once done, we enable the firewall with those new rules (and check that everything is OK with the status command) :

+```
+sudo ufw enable
+sudo ufw status
