this post is first time for me in this forum.
i am wondering if mikrotik is planning for the future to implement:
RFC 7597(Mapping of Address and Port with Encapsulation)
reason why i am asking - i currently evaluating HW/SW for acting as an home router.
you may not know some of Internet service provider in Japan already provide MAP-E solution long time ago to get internet connection more smoothly than pppoe connection.
Your ISP is a pure IPv6 provider, so you need a tunnel for the IPv4 traffic. Yes, it’s doable using the IPIPv6 tunneling in ROS which is supported by any Mikrotik Router. Just follow the instructions in https://www.iliad.it/docs/VoIP/Guida_Mikrotik_e_VoIP.pdf
Yes, you can use any MikroTik router other than just the RB4011. Iliad likely recommended it because of the SFP+ port, but you can get the RB5009, which is more powerful for a similar price.
