Any subdomains relating to protocols such as SMTP, FTP, or SSH will need to have proxying disabled and these domains/subdomains should point directly to the origin IP address to ensure functionality. You should configure your router to always assign this IP address to the Unraid server. Now you need to edit /boot/config/go which is a Bash script that Unraid executes automatically whenever the server boots up.
