Can no longer see Drobo NAS after switching to Apple Airport Time Capsule (2TB)

I have a PC that I use to watch movies on.  It accesses the movies on two Drobo NAS units.  The PC and the Drobos have always been physically connected to a router.  I manage the Drobos using Drobo Dashboard software.  The Drobos show up in my Network in Windows Explorer and I cannot map drives to them as well.

 

I also have a MacBook Pro that I use for wireless access.  I have the same Drobo Dashboard installed on this and I can also see the Drobos under Shared on my Mac.

 

I just switched my older router (D-link DIR 655) to a new Apple Airport Time Capsule (2TB).  Upon doing so I lost access to my Drobos.  I cannot find them on my PC.  They don't show up in the network and I cannot find them using their old UNC pathx \\Drobo-FS1\Public\ or \\Drobo-FS2\Public\.

 

In the midst of this I updated my Mac OS to 10.8.5.  The only reason I bring this up is that I now configure the Apple Airport Time Capsule with the Mac itself.  Now as per the Drobo support forums, I have ensured that under System Preferences\Security and Privacy\Firewall\Firewall Settings I have "Allowed" the DDServiced64.

 

Note that on my PC I can see all the wireless devices in my house.  Just not the hard-wired Drobo units.

 

 

Note to that when I was using my old D-link DIR 655 I was using DHCP and using static IP Addresses.  In fact I believe I entered these static addresses in the Drobo settngs themselves in via the Drobo Dashboard.  I think D-link uses different IP syntax like 192.168.0.1.  I think the "0" is the differentiator for D-link routers.  


I am trying to figure out if the issue is with: the new Apple Airport Time Capsule; a conflict between the Norton Internet Security that is on my PC (Ver: 21.1.0.18) and the Apple Airport Time Capsule; or could the old static D-link IP addresses that I configured the two Drobos with via the Drobo Dashboard be rendreing the units undiscoverable given that I am now using the Apple Airport Time Capsule [I have reached out to Drobo on this last question]?


Is there a Firewall or Traffic Rule setting on Norton that could in some way be conflicting with the Firewall settings of my Apple Airport Time Capsule?

 

Thanks
