GoodbyeDPI is a Windows command-line tool for people whose internet provider restricts access to certain websites through traffic inspection. It can be run directly or started with included command scripts, and it needs administrator permissions. Users can try the supplied settings first, then change its options to match the way their provider handles connections and domain lookups.

It offers a way to adjust connections when provider traffic inspection interferes with website access.

The utility handles inspection systems that send early responses and those positioned directly in the connection path. It can discard injected replies and alter the first packets of HTTP or HTTPS connections, including splitting packets and changing HTTP header formatting. Options also cover website lists and redirecting DNS requests to a resolver on an alternative port.

Features:

  • Filters injected redirects and connection resets
  • Splits initial TCP connection data
  • Adjusts HTTP header formatting
  • Sends decoy packets with altered network fields
  • Applies settings to specified website lists
  • Redirects DNS requests to alternative resolver ports
