Settings for EPICS clients:

  firewall-cmd --add-rich-rule="rule source-port port=5065 protocol=tcp accept"
  firewall-cmd --add-rich-rule="rule source-port port=5065 protocol=udp accept"

Additional settings for EPICS servers:

  firewall-cmd --add-rich-rule="rule port port=5064 protocol=tcp accept"
  firewall-cmd --add-rich-rule="rule port port=5064 protocol=udp accept"
  firewall-cmd --add-rich-rule="rule port port=5065 protocol=tcp accept"
  firewall-cmd --add-rich-rule="rule port port=5065 protocol=udp accept"

Channel Access does not use TCP on the beacon port (aka CA_REPEATER_PORT, ca-2, 5065). Opening it does no harm, but is not needed.
