nsr ports conflict

Hello,

We have a port conflict between a production application and Legato in our company on a client server (networker client). it is about port 8543. nsrexecd used this port also.

I have been reading some threads of people having similar issue in the past. Is the solution is to run against the client?:

for example: 

1) client_sever>nsrports -s -S 7937-8540

2) restart networker services

I read that 4 ports are usually used by nsrexecd in the case of normal networker clients (not having NMC or being a storage node) so I think this is a sufficient range.

my question are:

1)running this command on the client will not harm the configuration on the networker server and the other clients?

2) also, is there any additional steps that should be performed ( firewall config ) so nsrexed takes this modification into account?

3) is there a command with that skips specific ports?

Thank you
