The ungleich NAT64 infrastructure¶

Status¶

This document is WORK IN PROGRESS.

General¶

• We started with tayga in 2017 and switched to jool some time in 2019
  • tayga was cpu bound
• We run stateful NAT64 (1:n mappings)
  • __dcl_nat64_jool in cdist
• We run stateless NAT64 (1:1 mappings, aka SIIT)
  • __dcl_jool_siit in cdist

Setting up a new IPv4-to-IPv6 mapping¶

• Add mapping in __dcl_jool_siit/files/ipv4-as-a-service.conf
• Reconfigure routers:

cdist config router{1..2}.place{5..6}.ungleich.ch

• Be happy.
