Chunk Restrictor
The author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
This server-side mod prevent players from entering specific chunks via a configuration file, supporting specific Chunk Coordinates and FTBChunks claims.
There is 2 simple options, both bypassed by operators.


"Restricted chunks" are the chunks you manually private access based on the x and z coordinates of this chunk. You can find the Chunk Coordinates via this calculator or via the F3 debug menu. This is needing a space or a , to seperate the X and Z values properly.
The FTB Chunks compat can be enabled or disabled in the Chunk-Restrictor-Compats file located inside the regular config folder. You can use the compat under the ingame FTB Teams properties, it's encouraged to install the mod inside the client otherwise the names may appears wrong.

There is how the mod is working, skipping some details:
Every ticks the mod check if the player is inside a restricted chunk or a FTBChunks claim where they do not have permission to enter based on the properties. If the check is true the player will be teleported to the last valid position, if the check is false the player's last valid position will be updated in the NBT data. This may sounds like a laggy process that this really isn't and in comparaison greatly underwhelm everything happening each vanilla tick.
