IP forwarding on truenas scale

Hi newbie to Nas apps, linux and truenas
running truenas, latest version as far as i know, set up to run jellyfin, immich, have installed tailscale so i can access media on jellyfin or to upload media to immich except tailscale states truenas doesnt have ip forwarding so its not configured to let me access the installed apps outside of my home network, and solutions would be great as then i can look at adding offsite backups
