mafiosso 0 Posted December 11, 2008 Hi, i have a Dvr KPD-604 and is working fine, i want to know what port to open in the router`s firewall for audio. I tested the dvr in to my local network and i have live audio and video. When i put it out side my local network, i only have audio in playback mode. Can anyone help me or have any idea ?
