RouterOS IPv6 NAT?
2

Mikrotik uses kernel 3.3.5

I seriously doubt they will update that kernel version significantly until they release mikrotik 7.x

Why should you need any kind of NAT in IPv6? Protecting users from incoming connections? That will do any rule like ā€œdrop incoming connection if not related to any outgoing connection from client ipā€ you can built in iptables and ROS since ages.

4

Maybe greedy ISPā€™s are only giving out a handful of IPv6 addresses instead of large blocks?

5

Maybe some ISPs hand out dynamic IPv6 addresses, and you want some fixed addresses in your local network?
Maybe you could have 2 IPv6 providers and want fallback without changing IPsā€¦ you can imagine a lot of scenarios.

I think Ipv6 NAT is necessary for activate the hotspot service using IPv6 addresses.
Moreover, it some networks it is userfull to net map an IPv4 LAN address to IPv6 address (in SOHO).

Do you think this feature will be implementing the next MikroTik release 7.x ?
