Currently setting up NIM on a firewalled environment and multiple gateways. By following the ports need to be opened on the below link:
IBM NIM Communication within a Firewall Environment - United States
I have asked network team to open up firewall but omitted the 32,768 to 65,535 port as our security won't be able to open this big port ranges.
It seems that NFS by using mountd can be specified a specific port but TFTP specifically needs this high port:
tftp:
Client UDP <--> Master UDP 69
Client UDP <--> Master UDP (random port between 32768 and 65535)
Here the client communicates via UDP to the master's port 69. The port that the client uses cannot be predicted.
Then, the master responds from port 69 back to the same port that made the request.
I used the bidirectional arrow to represent this.
Then random UDP ports are chosen on both the master and the client to affect the transfer of data. Again bidirectional.
Does this mean that nim mksysb might work but OS restore wont?
