Connecting through the view client from home works but trying on my outside secondary ISP in the office does not. It did not work with an ATT network at a convention I attended but it does work with CenturyLink. I can't imagine any ISP blocking something like that so I can go ahead and rule that out. Everything that I have managed to read has either leaned toward DNS or routing problems, the only issue is they are not specific as to where they apply these changes.
I have started to create a new security server with just one NIC as a DMZ public IP and may try to start from scratch.
