Port 29120 is used for all communication among the Framework managers and the agents. Port 29120 is also used for communications among the Framework agents.
If firewalls separate your Privileged Account Manager machines, this port must be opened to traffic in both directions for NetIQ Privileged Account Manager to work properly.
The port is specified when the agent is registered with the Framework Manager. If you need to specify a different port because an application is already using port 29120, this new port needs to be opened in the firewall for communication.
NOTE:For RHEL 8.x, you can use:
firewalld: Use the firewalld utility for simple firewall use cases. The utility is easy to use and covers the typical use cases for these scenarios.
nftables: Use the nftables utility to set up complex and performance critical firewalls, such as for a whole network.
iptables: The iptables utility on Red Hat Enterprise Linux 8 uses the nf_tables kernel API instead of the legacy back end.
The nf_tables API provides backward compatibility so that scripts that use iptables commands still work on Red Hat Enterprise Linux 8. For new firewall scripts, Red Hat recommends to use nftables.
