Hello,

 

Has anyone else seen this issues.

 

Ive been playing with the system extensively.

And done even more TESTING. I believe the firmware has a bug.

 

I have my iot camera on my guest network.  They are port forwarded to an open port.  I am able to connect from the external ip:port number from a device on the guest network and external network, but not from the main network.

 

Let me explain.  

 

How you can test this. (Easy test. 5 MIN)

 

Setup your router with 2 networks (main/guest). NO other settings needed.

 

 

------‐-------TEST #1------------------

 

1. On the guest wifi connect a security cam utilizing rtsp

2. Port forward the local port to an unused external port

3. Try to connect to that camera from the guest network with a tablet/laptop on the GUEST network. Use the EXTERNAL IP address and new port assigned from step 2...... ........ you should be succesful

------‐-------TEST #2------------------

 

4. Change the wifi network of your laptop/tablet to MAIN NETWORK.

5. Type the same exact ip address:port used above into laptop/tablet...... ...... it wont connect

 

------‐-------TEST #3-----------------

6. Disconnect laptop/tablet from main network and connect to cellular (EXTERNAL network)

7. Type the same exact ip address:port used above into laptop/tablet...... ...... it successfully connects

 

-------------‐--------------------

 

 

I have also done extensive testing/analysis around the iot network/connecting thru a vpn/ device isolation setting.

 

Thank you
