This is a very simple plugin that redirects players (using the server redirect packet) to any minecraft server, even those not part of your network.
This does require the client to be on version 1.20.5 or higher, the server to be on PaperMC 1.21.9 (or another supported MC version) and the server that you are redirecting TO having 'accept-transfers = true' in their server.properties file.
To Transfer ALL players in the server to a new server, you would enter a command such as /redirect * play.example.com
To Transfer a specific player in the server to a new server, you would enter a command such as /redirect Steve play.example.com
This is a custom made plugin, so realistically I probrably wont ever update this unless this project gains popularity, which I am pretty certain it will not.
