HP OneView for VMware vCenter - Manual (Page 94)

A Firewall port requirements
To achieve full functionality, an Insight Control for vCenter server requires that the firewall ports
selected or configured during the installation of Insight Control for vCenter 7.0 server are opened
(inbound/outbound). The system on which the software package is installed needs to route via a
firewall to Onboard Administrators/ Virtual Connects.
Insight Control for vCenter uses outbound pings to determine if entities are available. Therefore,
ICMP ping must be enabled.
