Which ports to allow monitoring through firewall?

Which ports to allow monitoring through firewall?

Do I just need the following ports to allow OpManager to operate to devices on the other side of a firewall?:

SNMP ports 161 (for agent) and 162 (for manager).
WMI ports 445 and 135.
ICMP used for testing reachability.

Anything missing?

Thank you.
