From my nfso -a output, my nfs_use_reserved_ports=0.
Is there a way to fix the NFS server/client port range so that we could have NFS setup behind a firewall?
What are the best practice for NFS setup behind a firewall?
My security team was asking whehter NFS client supports keep alive feature, whereby NFS client connection will re-establish a new connection automatically after timed out? Anyway, is there any client session timed out settings on NFS server?
