Access home assistant externally through Duckdns with squid proxy sever

[SnowmanUT]

I have been trying to set up external access to my home assistant box through duckdns addon for home assistant and forwarding the required ports of 443 to 8123 on my Pfsense box but I can't get it to work. I'm a noob for sure with Pfsense but I have had it running with Squid Proxy server for a while but wanted to get this working for more home assistant features externally. I'm thinking squid is stopping this from working but not sure what I need to do to make it work. I followed the following websites to try to set this up but not sure on the Pfsense side of things why it doesn't work.

Any help would be appreciated.
