I have a server running locally and to ensure it is accessable from a local or remote connection it REQUIRES a split DNS configuration. This means that its domain name resolves to our public IP address when queried from the internet but resolves to the local IP address when queried from a local connection.
In the past I've used a Draytek router which supported adding DNS entries.
When we went over to using the smart hub I added a DNS proxy but it is excessive just to force one IP address and I'd like to use the hub's DNS HOSTS facility instead.
Only problem is when I put in the server's name the hub converts all the dots into dashes.
I'm just a one-man band and you have way more networking knowledge than me. I'm just good at figuring out stuff. Is the ONT optical?
