I tried to find this on the existing questions... I am using a Droid phone to try to see my DVR video cameras.
I have a static IP and a netgear router.
I checked the Disable Firewall for True Static IP Subnet Only box... I think that this makes gives my netgear router all control...
I have turned on Ping on my Netgear so I can ping it... That seems to work.
I then set my DVR to a static IP, and set up a port forwarding rule for port 5050, 6050, 7050. The DVR says that those parts are to do Command Port 5050, Media Port 6050, and Mobile Port 7050.
I downloaded IP Cam Viewer for my droid... I can turn on Wifi and connect to my internal IP address with port 5050 and see the cameras. Then if I turn off Wifi and try to connect to my external IP address with port 5050 but cannot connect.
Welcome EvergreenJeff. Comcast does not block ports 5050, 6050 or 7050. We have that the SMC is configured with the correct bootfile and IP. I am including a Netgear Link that contains configuration information for a number of Netgear routers. For additional assistance please send me a PM with your contact info and we can have a Tier 2 agent work directly with you.
