For the most part, it’s pretty painless. Unless you have a super complex setup you’ll be fine.

Oh, then something is wrong with your DNS. You should have a forwarder setup, then you don’t need two ABS servers.

Sigh…

I hate to add to this by saying I also have the same issue and not provide anything helpful.

Things that made it better?

1. Dual zone DNS. When I’m in the house or on my VPN I don’t need to go out and back in.
2. Disable Cloudflare proxy, or whatever it’s called that hides the endpoint IP.
