I have been banging my head to find out why I was not able to access my HA remotely after setting up the port forwarding.
Then I found out my Fibre connection is behind CGNAT !! Arghhh. So, no port forwarding is possible and my ISP basically said they’re aware but no ETA of allowing this.
So… what’s the other way of getting this to work? I have DuckDNS all set up. Just that I can’t access it externally.
Alternatively, you can also use a VPN like tailscale, if your only goal is connectivity between your phone and HA, not actually opening up your HA to the world
