SharpTJ1 0 Posted September 15, 2016 Currently, I can not get regular Internet service where I live. I do have an unlimited 4G hotspot through Sprint. Get very good speeds with it. All ports show up as "stealth" when I do a scan. I have tried forwarding them correctly 80 and 37777 and also tried changing them to non-traditional ports, with no success. Is there anyway to make this work using a dedicated NVR? Share this post Link to post Share on other sites
ChengXin 0 Posted September 16, 2016 Is your NVR pointing to the 3G router as a a gateway? Share this post Link to post Share on other sites
SharpTJ1 0 Posted September 16, 2016 Yes, it is pointed at my cradlepoint router as the gateway Share this post Link to post Share on other sites
ChengXin 0 Posted September 16, 2016 Sorry. In that case, I cannot offer further help without remote access to the router and camera. Another possibility is that some ISP block such ports. Share this post Link to post Share on other sites
SharpTJ1 0 Posted September 16, 2016 I think it is Sprint blocking ports....when i do a port scan on my ddns it only shows port 80 and 21 (sometimes) open. I have forwarded both ports to my NVR and even tried putting the NVR in the DMZ Share this post Link to post Share on other sites
