Ports required for MLM communication across a firewall

[Lisa.H.Chu@chase.com]

Hello All,
     Does anyone have the follwoing scenario implemented:

     Netview Server in the DMZ with two MLMs (one is located on the internal
side and the other one is on the external side).  The question is what other
ports are required for the MLMs to communicate with the Netview server besides
port 162?  The MLMs will be doing discovery in its own network and will report
back to the Netview Manager and will also send traps to the Netview Manager.

     Does using APM for policies and poliy distribution require any other ports
to be open?  Any comments would be appreciated.
