As per WP 11826 I reconfigured the firewall on h1daqgds0 and h1daqgds1 to allow transfer of the live CDS data to a new nds2 node in the LDAS cluster.  This was a simple update of the config with no impact on the daqd or existing data streams.

When the new nds2 node (nds-4) is ready I will enable the data stream.  There is no addition configuration required for this on the h1daqgds machines.
