Features

Security System

Protect your network before malicious connections even reach your backend servers.

• Intelligent VPN & Proxy Blocker:

• Blocks connections via anonymous networks (VPNs/Proxies).

• NEW: Uses an intelligent Caching System (stores results for X minutes) to save API limits and prevent join lag.

• Requires a free API key from proxycheck.io.

• Persistent Punishments (SQLite):

• NEW: Temporary bans (e.g., triggered by Anti-Bot) are now stored in a local SQLite database (database.db). Bans remain active even after a proxy restart!

• Country Blocker (GeoIP): Whitelist or Blacklist specific countries.

• Anti-Bot & Anti-Exploit:

• Detects inhumanly fast connection attempts.

• Blocks invalid usernames.

• Prevents packet exploits at the proxy level.

• Multi-Account Protection: Limits the number of players allowed to join from the same IP address.

Discord Integration (NEW)

Connect your proxy to Discord via Webhooks:

• Notifications for VPN/Bot blocks (includes IP and username).
• Notifications for Maintenance Mode status changes.
• Fully asynchronous – your server will never lag, even if Discord is slow to respond.

Global StaffChat (NEW)

Communicate with your team across all servers:

• Command: /sc <message> or /staffchat <message>
• Toggle Mode: Use /sc without arguments to automatically send all your chat messages to the staff chat.

Maintenance System

• Custom MOTD: Displays maintenance status directly in the server list (supports color codes).
• Auto-Kick: Disconnects players without permission during maintenance.
• Bypass: Staff members with permission can still join.

Queue System

• Redirects players to a queue server if the target server (Lobby) is full.
• Priority support for VIPs/Staff.

2. Place the file into the plugins folder of your Velocity Proxy.
3. Important: Ensure Java 21 is installed.
