Firewall and communication configuration#

Before you install the server, you must ensure that servers, agents, and other systems can connect to each other through your networks and firewalls.

The following diagram shows the main default ports that are involved in communication between agents, agent relays, and the server.

The following diagram shows the default port numbers that HCL™ Launch uses for communication. Most of these ports can change depending on your choices at installation time. The following diagram is only a summary of the defaults.

As shown in the diagram, agents can connect to servers directly or through agent relays. You must ensure that the agent communication can get to the server through any firewalls or other limitations.
