I have 3 2132 cameras. When setting them up for port forwarding I'm. Having a issue. I set the ips up and as soon as I change the port I cannot log onto the camera on my home network. I had them set up for dns forwarding and they we're working fine for remote viewing and all of the sudden the stopped working. So say my ip 192.168.0.50 and ports are at factory setting I can log onto fine. As soon as I set ports to 8001 and 81 I cannot view on my home network. When I type 192.168.0.50:81 I should be able to log onto cam but I cant. In fact it does not even show up on the sadp software. I'm at a loss. Please someone help
