 To open these ports on AWS, go to the EC2 console, and click on *Security Groups* in the left margin. Then look for the *Security Group* for the *Instance* on which you installed Galera Manager. Edit the *Inbound Rules* for that group to open those ports. When you are finished, the *Inbound Rules* will look something like the screenshot below:

 You may have noticed when looking at the lists of ports above and in Figure 1 that they do not include port 3306 and other ports used by MySQL, MariaDB and Galera Cluster. Galera Manager does not need them to create and monitor a cluster and nodes. Those ports are needed on the hosts of the nodes. So separate *Security Groups* will be needed for them.

The other three ports are used by Galera Cluster and the nodes to communicate with each other and synchronize lagging or new nodes that join the cluster.

 You might be tempted to tighten security more, to create one *Security Group* to be used by all hosts and in it to specify the IP addresses of each node for ports 4444, 4567, and 4568 |---| perhaps because of the default description, *No Restructions* for each of those rules. Along these lines, you might also change ports 9100 - 9104 to the IP address of wherever Galera Manager or ``gmd`` is running. You would have to leave port 3306 accessible from anywhere, though, so that MySQL users and clients can access the databases.
