Overview

Will the LEM agent work with just the agent side of the ports opened 37890-37892 on the firewall?
          note: these are the destination ports going to the LEM appliance, source ports for traffic going to the agent.
Will ports 37893 - 37896 need to be open?
          note: If the agent is version pre-6.3.1-hotfix-4, yes. If agent is 6.3.1-hotfix-4 or later, these ports are not used.
               LEM agents use ephemeral ports 35000->50000 instead (source from agent to LEM, or destination from LEM to agent.

Environment

LEM 6.2 & 6.3.1

Detail

For the agent to work correctly, ports for both sides of the communication must be open.
If the firewall is located on the Windows server/workstation with the agent installed, only ports 37890->37892 need to be open, but be sure to open ports on all 3 firewall profiles (Domain, Public, Private).
If the firewall is on the network segment separating the agent from the LEM Manager, ports may need to be open both ways.

This is the requirement for the agents to be able to establish a secure connection to the LEM manager.


If the agent is version pre-6.3.1-hotfix-4, the following ports must be open:
     Agent -> LEM Manager  ==>  source ports 37893->37896 & destination ports 37890->37892.
     LEM Manager -> Agent  ==>  source ports 37890->37892 & destination ports 37893->37896.


If the agent is version 6.3.1-hotfix-4 or later, the following ports must be open:
     Agent -> LEM Manager  ==>  source ports are Ephemeral ports & destination ports 37890->37892.
     LEM Manager -> Agent  ==>  source ports 37890->37892 & destination ports are Ephemeral ports.
