Hello, i recently setup my router to port forward to a home automation device...everything was working fine until i recently installed 3 IP cameras. Now i get a shuffle of the automation device or either of the cameras depending on when i hit my dyndns IP. Could UPnP being turned on for the cameras be messing with my router and causing these issues? It's the only thing i could think of given my setup.
Sorry, i'd test it myself if i were at home but i'm away for awhile and searching for an explanation anyway.

I personally always turn UPnP off since it can cause security issues.
