Whether to enable Jool, an Open Source implementation of IPv4/IPv6 translation on Linux.
Jool can perform stateless IP/ICMP translation (SIIT) or stateful NAT64, analogous to the IPv4 NAPT. Refer to the upstream documentation for the supported modes of translation and how to configure them.
Enabling this option will install the Jool kernel module and the command line tools for controlling it.
