Issue

  • After installing Satellite 6 on Red Hat Enterprise Linux 8, a few network ports need to be opened.
  • On RHEL 6, 7, 8, and 9, what ports need to be open for Satellite 6?
  • Is there a list of all the required network ports for the Satellite, Capsule, and managed hosts, as well as the start and endpoints of each communication path? This could be used to determine the required network access for the deployed Satellite, Capsule, and managed host topology.
  • What is the network communication flow from the client to the Satellite and/or external DNS/DHCP?

Resolution

The most complete list of ports that need to be open is found in the respective installation guides:

Note: If the outgoing firewall on the company network uses host name filtering, certain hostnames need to be allowed. See How to access Red Hat Subscription Manager (RHSM) through a firewall or proxy for more information.

Follow the procedures in the guides to configure the host-based firewall on Satellite Server and Capsule Server's base system. Use the port tables in the guides to plan how to configure any network-based firewalls.
