In this repo, you can find a prototype of a HA WAF with Lets Encrypt certbot for HTTPS

• set allowed countries
• set local LAN
• set allowed ISP ranges

• set server_name
• set cert paths
• set upstreamServer URL

• try a "dry-run" init-letsencrypt-dns.sh init-letsencrypt-dns.sh <comma-sepparated-list-of-3rdlevel.duckdns.org> <email> <duckdns-token> to avoid hitting request limits, staging LE platform is used to check functionality

• if successful, repeat and add 4th parameter = staging with value 0 = uses live API init-letsencrypt-dns.sh <comma-sepparated-list-of-3rdlevel.duckdns.org> <email> <duckdns-token> 0 note: docker-compose up -d is run at the end to launch the reverse proxy & automatic (daily) certbot renewal

• configure HASS reverse proxy access - see use_x_forwarded_for, and trusted_proxies at https://www.home-assistant.io/integrations/http

• no root nginx
