network port

Hi,

I install a SEPM 14 with embedded database. The server and clients are on different vlan

I ask to my network admin to open this network ports :

- 137,138,139,445,22 between server and users (for the deploimeent of the SEP client)

- 8443, 9090 between server and tech IT computers (for the console)

- 8014 and 443 between server and user (for the communication of the agent)

My question is : is it mandatory to open others ? 8445,8446,8447,8765,1100. I don't understand utility of this services

Thanks
