The Firewall port 29120 is used for all the communication among the Framework managers and the agents. Port 29120 is also used for communications among the Framework agents.
If firewalls separate your Privileged Access Manager machines, 29120 port must be opened to traffic in both directions for Privileged Access 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 if the port 29120 is already in use, 29120 port must be opened in the firewall settings for communication.
NOTE:For RHEL 8.x, you can use:
firewalld: Use the firewalld utility for simple firewall use cases.
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 backend.
The nf_tables API provides backward compatibility so that the scripts that use iptables commands still work on Red Hat Enterprise Linux 8. For new firewall scripts, Red Hat recommends to use nftables.
