Your Terraria server is a PC dedicated server. PC (desktop) and mobile players can join it, as long as they are on the same Terraria version as the server. Consoles cannot join yet: Switch, PlayStation, and Xbox players have no way to connect to any Terraria dedicated server, on any host. Re-Logic has console crossplay in active development, and nothing about your server needs changing when it arrives.
PC (desktop): yes. Everyone on the same Terraria version as your server can join by address.
Mobile (iOS, Android): yes, using the same Join via IP flow, as long as the mobile app is on the same Terraria version as your server. Mobile releases land separately from PC ones, so in the days after a Terraria patch a mobile friend can be turned away until mobile catches up.
Console (Switch, PlayStation, Xbox): no. Console Terraria has no way to connect to a dedicated server yet.
Console players can still play with friends on the same console platform through Terraria's own in-game multiplayer, just not on your server.
Console Terraria has no field for a server address, so there is nothing for a console player to type and no setting that unlocks one. That is a Terraria rule, not something we control.
Re-Logic and DR Studios are building console crossplay in two phases:
Phase One (1.4.6): console players can join dedicated servers over the internet, and join LAN sessions across platforms.
Phase Two: players share a session ID or join code to play together on any platform and any network.
Phase One is the one that matters for you, since it is the phase that lets consoles reach a hosted server. Re-Logic has not given a release date, so we will not guess one.
Your server runs the official Terraria dedicated server build, and Haptic tracks each new one Re-Logic publishes; a Restart from the dashboard is what applies it. When the console crossplay release ships, that same restart is all it takes. There is no crossplay toggle to wait for and no need to rebuild your world.
In Terraria, players choose Multiplayer, then Join via IP, and enter the address and port from your server card (Terraria asks for the port on its own screen). The full walkthrough, plus the version rule and the tModLoader rule that turn players away more often than platform limits do, is in Terraria: can't join your server?.

Mods. No mod runs on console Terraria, so a server-side mod cannot open a door that the console version does not have.
Changing settings, region, or the server address. The limit is in the console game, not in your server.
Switching hosts. Every Terraria dedicated server on the internet has the same restriction.
