OK, so if I understand correctly, we need the following rule in firewall.

Networker server to client :    
TCP/UDP
7937 - 7944 (for services)
10000 - 10100 (for connection) -  I believe 100 would be enough

Client to Networker server:
TCP/UDP
7937 - 7944 (for services)
10000 - 10100 (for connection)


The only part I didn't understand was whether or not the nsrports need to have 
the same values to be able to work with the firewall rule..

Currently, NW server and that client have the default values.
service ports : 7937 -9936
connection ports : 0-0

If I update nsrports on the server, what would happen to the storage nodes and 
all other clients that also use the default range ?
