Introduction

Jool is an Open Source SIIT and NAT64 for Linux.


Status

  • The most mature version is 4.1.6.
  • The second release candidate for version 4.2.0 is also available now.

Due to a temporary resource shortage, the project’s development has slowed down to essential maintenance. No new features are expected to be developed during the first half of 2021 (at least), but bugfixing and support will remain active.
