Router to do NAT hairpinning

[aceindy]

What I did before I got my hairpinning working:

Local and remote access to HA together

Add your external domain name to your internal network (on your local dns server (== router?)) f.e. domain.mine Bind your HA’s name to IP (f.e. home) Then use https://home.domain.mine as external URL and https://home.domain.mine:8123 as internal URL
