1. As long as you are connected to the Wi-Fi of the Deco you should be able to use the Deco app to manage it.

2. Limits on entries are usually due to the available resources of the device.

3. The app and ID are there for simplicity with respect to the Deco system. 

4. Not from a PC, you will need the app from now to the future.

5. No, you just need to have an Ethernet cable that provides an internet connection to the main Deco.

There is a beta out that does allow access via a web page on a PC.   It also increases the port forward limit to 64.  It is unclear to me how long it will be before that beta goes GA.

Unfortunately response 1 seems to be inaccurate as I cannot access the DECO unit unless it has an active internet connection. I verified this by disconnecting the WAN feed from the ISP and could not access the DECO wirelessly. Basically, if the LED went Red I had no ability to get into the DECO at all.

Are you running the Deco in AP Mode? Initially, when you set up the Deco it needs the internet, but it should be manageable when missing the internet after the network is running

With respect to the port forwarding, it looks like the v2 will be getting the expanded port forwarding rules as the v1 so you will be able to go up to 64 entries with the next firmware.
