I HAVE AN AVC796 DVR WHICH I BOUGHT 2 YRS AGO. IVE SET UP THE REMOTE MONITORING THRU DYNDNS AND EVERYTHING WAS RUNNING SMOOTHLY. NOW I CANT ACCESS IT THRU VIDEO VIEWER OR BROWSER. I HAVENT CHANGED ANYTHING. I DID TROUBLESHOOTING RESET TO DEFAULTS, I CAN ACCES IT THRU LAN BUT WHEN I RECONFIGURE IT NO LUCK... IS DYNDNS HAS SOMETHING TO DO WITH THIS?
