Ports needed by ePO 4.x and ePO 5.x for communication through a firewall

The following tables display the ports needed by ePO for communication through a firewall:

Bi-directional means that a connection can be initiated from either direction
Inbound means the connection is initiated by a remote system
Outbound means the connection can be initiated by the local system

ePO 4.6.x and 5.x

Port	Default	Description	Traffic Direction
Agent-server communication port	80	TCP port used by the ePO Server service to receive requests from agents.	Inbound connection to the Agent Handler and the ePO server from the McAfee Agent. Inbound connection to the ePO server from the remote Agent Handler.
