I would guess that, if this was set up and working correctly, I should now just be able to test it by typing in my current IP address: https://xx.xx.xx.xx:8123/ and get the HA login page? This just gives me a timeout. So does this mean the problem is with my port forwarding? I just need to know where to start from to try and resolve this.
If your WAN side IP address on the router is not the one external systems think you are then your carrier is probably NATing you. Bit of a pain as it can break a lot of things.
I’m using Utility Warehouse (piggybacks EE) mobile 4G router for my broadband. From what I have read, they use CGNAT. I notice that my IP address seems to change regularly, even though my connection has not been off.
Have sent a ticket in to UW to ask if they can give me a public or static IP. I’m not holding my breath though as it’s a pretty no frills service (£18pm for unlimited data), and a piggyback network.
@siwilson it’s as I feared. I think there is a cloud service you can use for HA, but not worth it for the amount of times I need remote access.
Openreach have been promising us cable broadband for the last 5 years. A couple of months ago they actually put cables in to the outside of the building. Now they just need to connect them to the main network. EE 4G has been pretty unreliable, so will be happy to switch when we can.
I have used Nabu Casa for a year or so now and it works very well for me. Apart from solving a problem, the subscription is also giving back to the HA team. IMO it’s a small price to pay.
