📋 About This Mod

# Network Blocker ## Overview Network Blocker is a utility mod that allows you to block unwanted network connection. By default, only connections to Minecraft services are permitted, which are necessary for authentication, etc. IP connections are also allowed, but this can be changed in the configuration file. By observing the log, you can know which connections are blocked. This mod is currently in beta. There might be connections it cannot detect and block, and it should not be considered as a comprehensive security measure against malicious mods. ## Configuration You can find the main configuration file in `config/networkblocker/config.toml`: ```toml #When enabled, connections that are permitted will be logged logPermitted = false #When enabled, connections that are blocked will be logged logBlocked = true #When enabled, stacktrace will be logged logStacktrace = false #When enabled, direct IP connections will be allowed even if they are not in the whitelist allowIP = true #Set to true to add some useful domains to the whitelist. The current defaults are: # #minecraft.net #minecraftservices.com #minecraft-services.net #mojang.com # #You can add additional domains to the whitelist using the file in the config folder. useDefaultWhitelist = true #Specifies the method used to block network connection. Valid values: #REDIRECT: redirect addresses to 0.0.0.0 #THROW: throw an exception blockMethod = "REDIRECT" ``` You can add domains to the whitelist in `config/networkblocker/whitelist.txt`: ``` # Add additional domains to whitelist in this file, one per line # Lines starting with # will be ignored. # # Example: minecraft.net ```
