This plugin is designed to be a simple and efficient alternative to OnlyProxyJoin, fixing BungeeCord's IPForwarding issue. It functions as an roadblock that only allows whitelisted connections to join, with easy setup and commands to manage the plugin.

Features:
1. Option to make server appear offline to scanners.
2. Connection Blocking

How to use :

1. Install ConnectionWhitelist on every SPIGOT server. This plugin is NOT installed on BungeeCord.
2. (Optional) Enable IP Forwarding in Spigot/BungeeCord
   
3. Add your whitelisted IP(s) in the config or via command
4. Reload plugin if adding IP(s) manually
5. Connect to the spigot server through BungeeCord

Assuming you did this correctly, ConnectionWhitelist will detect if you are using a whitelisted IP and allow you to join. It will block all other IP Addresses.

Commands :
/cwl - Gives you a help of other commands
/cwl add <ip> - Adds the IP to the whitelist
/cwl remove <ip> - Removes the IP of the whitelist
/cwl list - Lists all whitelisted IPs
/cwl reload - Reloads the whitelist config.

Permission node :
cwl.admin - Access /cwl command

Version compability :
ConnectionWhitelist 1.0 BETA : 1.8-1.20+

Future Updates:
Working on adding SQL compatability to sync whitelisted IP(s) between servers if wanted.

Notes:
1. Feedback is appreciated
2. Feel free to help improve the plugin!
