Moving this to the iCam Pro forum...
I am running iCam Pro (the latest version).
Up until this week, I was running with an Airport Extreme router. I just replaced that with a Netgear Nighthawk 7000 router.
I can connect to iCam if I'm on my iPhone on the local network, but if I disable WIFI and go to LTE, it seems like I can't connect (I get the "No Sources Found") message.
My router is getting a public IP address from Comcast, there is no double-NAT. I tried both using "Auto-Config Router" (UpNP on the router shows that the ports 13000-13003 were negotiated successfully), I've also tried static port forwarding to the machine running the server.
Is there anything else to try? I really don't see the need to run a proxy, my assumption is this is a setting in the router?
