Hi Mat, I have been posting on here and others have responded but I still have not figured out a working answer. I want to set up a secure camera system with openvpn at a remote site that only has internet available via a hotspot. Actually Att is the only one that has good coverage there too. I have tried a MR1100 Nighthawk hooked to a Asus Rt-N66u router to the dvr. But was never able to get pass the openvpn set up apparently because aat is not providing a public IP. I only get IPv4 from them as well. I am not set on this arraingement, one guy suggest a ras-pi system but I am not sure that will be any better. There must be a way to set up a camera system at a site with only cell data with some sort of hardware combo. If you have any ideas on this I will appreciate hearing them, Thanks.
