help with forwarding for home assistant
-
I think maybe I found the issue. I was trying to connect from the same LAN using the external IP. Don't understand why that doesn't work but if I connect from my iPhone via LTE I'm successful.

If you can't see anything in the log maybe the port is blocked by your ISP.You Packet Capture from the Diagnostic menu to investigate.
Take a capture on WAN interface, set the port filter to 8123 and attempt to access it from outside.
If you get nothing there, the packets don't reach your WAN. -

So its working as expected?

No idea how you have done that.

Just a browser window and enter <MyWANIP>:8123
This works from outside my local network but not internally? Not sure why?
The port is being forwarded though. Thanks for your help. -

This only works with NAT reflection.
You can activate it in a single NAT rule or globally in system settings. However, its recommended to better use hostnames and split DNS. -

Like this?

Why would you want to expose your home assistant to the public internet? Doesn't seem like a very smart thing to do from a security point of view..
-
Maybe use IPSEC or OPENVPN instead of exposing your server directly to the WAN.

Yes, using pfSense for DNS resolution presumed. So can access the home assistant with the same host name from within your network as well as from outside.
However, security concerns are not regarded with this recommendation. -
Is there really a security concern? I'm asking this as a legitimate question. I only have a basic layman's knowledge regarding network security but I have a very strong password set for HA and would think that it would be adequate. Maybe that's not true?

I have OpenVPN setup on my iPhone but at the time I set it up I couldn't find a way to keep it active. Maybe that has changed now (it's been a few years)?

Why do you think you even need to open the port? There should be zero reason for opening inbound ports to control your home smart things while outside your home.. They phone home (company servers) and you control via that connection.
I can turn on/off my lights, change the temp on the hvac, etc. without having any ports open.
If your using some home grown thing - that you need to talk to while remote, then yes vpn would be the secure way to do that.. Not opening it up to the whole internet..

My iOS app fails to connect without a connection to my local network.

Yes

Yeah you would want vpn then... If they server doesn't make a connection to outside services, like alexa, google, all the other 3rd brand lights and switches, and etc.. That you can use to control your devices. VPN is the way to do it securely.

"Just putting a port up is not secure. "They recommend using ssl - but that still leaves it exposed.. From a security point of view you should setup vpn on your phone to your pfsense box.. Then you can access your remote assistant through the vpn.. This does not expose it to the public internet and anyone hitting that port.

They do have a paid service for this but I would rather connect manually (turn the vpn on/off) and save the money if I can't find anyway to keep the vpn active.

Well the vpn could be set to always be active.. But turning on and off is just a single click.. On your phone

Right now I have ssl (lets encrypt). I have OpenVPN installed on my iPhone but it tends to disconnect when changing networks and won't connect at all when I'm connected to my local network. I see that the OpenVPN app now has functionality to try and re-connect but I'm not sure what those continuous re-connection attempts will do to my battery life and network performance.

You don't need it while your on your local network... Just turn it on when your away "and" you want to do something with your home assistant. Its a click to turn it on.
Do what it is you want to do and then disconnect it - click.
I would not suggest you open your home assistant to the public net - it is not secure be it your using https or not..
Here is some info about how often this port is scanned..
