What ports do i need to open in my Sonicwall TZ205 to get back to my mac to work properly. Snowcap like most commercial grade firewall's does not implicitly support upnp, so I need to open ports and enable port forwarding. What ports do I need to open?
Mac Pro, OS X Mavericks (10.9.2), Server 3.1 installed

Thank you for responding, but this really doesn't answer my question, I've tried to use the info embedded in the table of all TCP/UDP ports that apple uses with no success. What specific tcp/udp ports must be opened and forwarded for Back to My mac to work properly.
There is a table in this article which shows what ports Back to My Mac uses.
TCP and UDP ports used by Apple software products - Apple Support
The gateway must support either UPnP or NAT-PMP. Otherwise BTMM won't work.
Sadly, it appears you are correct. I've tried opening the tcp and udp ports listed in the link from Eric (which I have tried in the past) forwarded them to the Mac Pro I specifically need to access externally and as usual, nothing.
sonicwall and back to my mac
