Filters sent/received packets
This is a Minecraft Fabric mod that allows you to configure what packets are sent/received.
The mod filters the sent/received packets, by default (default config) it does nothing.
⚠️ Note that since it directly rejects/filters the sent/received packets (as configured), it may break some mods or vanilla systems, especially if you filter the packet identifiers (the first option), changing the other options probably won't break the vanilla game. Configure carefully!
The entire mod is configured through the Mod Menu UI with helpful tooltips; note that each change to the packets (rejecting or filtering them) is logged to the console. Below is a short description of every option currently there:
Control which packet identifiers are allowed.
For a list of all of them see the Minecraft Wiki article on Java Edition packets, specifically resouce in the Packet ID field of any packet. Note that you need to prefix the id with minecraft: namespace, for example minecraft:custom_payload.
Control which custom payload packet (aka plugin message or channel) identifiers are allowed, sent by most of the mod/plugin loaders and some of mods/plugins.
You can select the setting Use from "Registered channel identifiers" option below to also apply the filters from the respective option.
For a list of some of the identifiers see the Minecraft Wiki article on plugin channels, or the respective mod/plugin documentation for the sent packets. Again, like the packet identifiers, don't forget the minecraft: or some other namespace.
The Respond to rejected received query requests should probably be enabled, as to not break the handshaking flow.
Control which channel identifiers in minecraft:register, minecraft:unregister (used by Bukkit, BungeeCord, Velocity and Fabric API) and c:register packets (used by FabricMC, NeoForged, PaperMC and SpongePowered team) are allowed.
You can select the setting Use from "Custom payload identifiers" option above to also apply the filters from the respective option.
You can deselect the Send/Receive empty channel lists options to not send/receive empty channel lists.
For a list of some of the identifiers, again, see the Minecraft Wiki article on plugin channels.
What packets should be logged - regardless of if they're rejected or not. By default none are logged.
What custom payloads should be logged - regardless of if they're rejected or not. By default none are logged.
