I’m trying to give users access to do their timesheets from home using a web browser. I have set this up in the accounting software that runs on a server on our local network.
I want the users to go to email@example.com, . Do I add an A record in the DNS called firstname.lastname@example.org point it to the public IP address of the firewall for that entry?
I will then set the firewall to forward the request to the server on the internal network. Is this correct as far as name resolution of email@example.com?
