Packet Ward Mod (26.3, 1.20.1) – Keep Scanners and Abusive Bots

Packet Ward Mod stops known hostile connections before they reach Minecraft. It checks each new connection on the server and quietly drops sources known for scanning or abuse. Bad traffic gets nothing useful from your server, so its resources stay free for real players.

Features:

• Server-Side Only: You do not need to install anything on the client.
• Block Levels: Pick a level from 1 to 5, or use level 0 to turn filtering off. The default is level 4.
• Safe Fallback: If the lookup service is down, the mod lets the connection in and acts as if it is not installed.
• Privacy First: Connecting IP addresses never leave your server.
• Trusted Proxies: Works with PROXY protocol v1 and v2.
• Checks new connections before Minecraft starts its handshake.
• Drops sources already known for scanning or abuse without giving them any reply.
• Creates an anonymous lookup prefix on your server, gets possible matches, then confirms the full match locally before it decides.
• Does not send player names, UUIDs, joins or server activity anywhere.
• Does not log network identifiers.
• Rate limits have their own policy and deny connections by default.
• Comes in modern versions for Fabric, NeoForge or Forge, and these use PolyLib.
• Offers standalone Forge builds for Minecraft 1.12.2 and 1.7.10.

Configuration:

• packetward.json5: a commented file where you change every setting of the mod.
