[Jool-list] Ipv4 -> ipv6 <-ipv4

[Nico Schottelius]

Good morning Ara,

that is very much possible, f.i.:

IPv4Host     -- Translator      -- Forward packet                   -- 2nd translator  -- 2nd IPv4Host
192.168.1.4     192.168.1.1        src = 2001:db8:1::192.168.1.4       192.168.4.1        192.168.4.4
                2001:db8:1::1      dst = 2001:db8:4::192.168.4.4       2001:db8:4::1

This involves SIIT twice and at ungleich we call these scenarios "IPv4 islands".

Best regards,

Nico
