Containers:

• Client: Represents typical client device, sees typical dual-stack with private IPv4 and public IPv6
• Router: Represents FF node, routes IPv6 and performs CLAT 4->6 translation for its clients
  • Variant 1: router-jool, uses Jool SIIT for translation (requires jool kernel modules loaded on the host)
  • Variant 2: router-nat46, uses nat46 kernel module for translation (requires nat46 to be loaded on the host)
• PLAT: Performs NAT64 translation using a public IPv4 pool
  • Variant 1: plat-jool, uses Jool for translation (requires jool kernel modules loaded on the host)
  • Variant 2: plat-vpp, uses VPP for translation
    • Note that the setup here is kept very simple, and as a result shows poor performance. A proper setup would use polling mode, pinned worker threads and TAP interfaces to connect to the kernel network stack (or even better, DPDK on hardware).
• Gateway: Represents FF gateway, is connected to Router, PLAT and Internet, routes between them
• Internet: Represents internet services, answers to pings and TCP connections to port 1234
