I have connected my security DVR via Ethernet to my router. When I log into the router it sees it as an unknown Ethernet device and it has an IP. Neither of my PC's, wireless desktop (Win7), and laptop (Win10) can see it on the network. Both PC's can ping the DVR. The DVR uses Media Port 9000 and Web Port 80 by default. I have Win settings for sharing (PC's can see each other). I run Norton 360 and looked at the settings for sharing and everything looks good. Is this a port problem or a Win problem? Thanks!!
