I'm ok on Wi-Fi, but would like to set up for remote access.  As a novice the more I read, the more confused I get.  Where do I start, and what do I need to do?  I have a dir-655 d-linc router.  I believe it is a UPnP router.  Is it only the ISY's IP that I need to reserve, or do I include my PC as a reserved device?  In the ISY, do I need to go to file/Enable Internet Access?  Using Mobilinc to access.  My URL does not yet display a port, only four octets.  Do I need to set up a static IP, or is it the same as a reservation on my router? 
Any guidance would be greatly appreciated.
