which port and protocol is used to let NBU master server ping my laptop

Hi,

My NBU master server is Redhatlinux65.

I installed NetBackup - Java Version 7.6.1 on my laptop which is Windows 7.

There is firewall which forbids me to ping my laptop ip from NBU master server.

Can anyone tell me which port and protocol is used in such case?

Regards,

Lacey
