The app is terrible.  It glithces out every few clicks.  Trying to set up port forwarding for some services, and it is prompting to set a fixed IP which was already done through Address Reservation Section.  So I deleted the reservation, and tried to follow the port forward wizard and tried to re-create the reservation during that process and It just errors out and won't complete.  At this point I am unable to create any new Address Reservations at all.  Attached is the wonderful error that I keep getting.  Shame to pay for a fleet of products like this and have issues doing these simple tasks.
