I have two IP Cameras (Not their real IPs):
IP Cam 1: 192.168.1.200
IP Cam 2: 192.168.1.201
I use No-IP to map my ISP IP to a static hostname.
I can access my cameras externally using the No-IP hostname, with no issue.
When I am on my local network, I cannot reach them using the No-IP hostname OR IP address of the ISP.
I can access them via their internal, private IP addresses 192.168.1.200/201 and their corresponding port numbers.
What am I missing? In the app I use I have each camera twice; once using the No-IP hostname, and once using the internal hostname, so it gives me access when I'm external or internal.
How can I only have each camera once, using the external hostname address? I am guessing there is some kind of routing issue, internally it cannot find the external hostname. Do I need to add some kind of DNS entry? I am running an Asus router, running Merlin.
