Description

DWL provides a whitelist feature that allows you to restrict access to servers to specific addresses, thereby helping to defend your servers against malicious port scans from the internet.

Features

  • Supports configuration file ./config/dwl-config.json

  • Command /dwl reload to reload config

  • Prevents malicious scanners from discovering your server's MOTD

  • Prevents malicious players from directly connecting to your private server via non-domain names and port numbers (by sending erroneous data packets to cause network protocol errors, thus making the attacker believe your server is inaccessible).

Config

{
  "list": [
    "mc.example.org:12345",
    "mc.example.org:22222",
    "simple.example2.org",
    "*.example3.org"
  ]
}
