Hi All,
I would like to have my server’s ipv6 address in the DDNS configuration, as (if I understand ipv6 correctly) there is no NAT/PAT with ipv6 any more. Or is there a best practice to advertise ipv6 services through Mikrotik’s public ipv6 address?
Any advice is appreciated.
You don’t need NAT with ipv6 , you normally get a /64 or /52 prefix that is enough for all your connected devices.
/64 is most often not enough … each LAN subnet needs separate /64 prefix while those brain-dead ISP who provide only /64 prefix often require that router uses one address from the same prefix on WAN interface … which disables you to use any of that prefix on LAN sider of router.
So minimum is to get /60 prefix (which means 15-16 /64 subnets), many ISPs hand out /56 (plenty of subnets). Some even hand out as short as /48, but that’s IMO too large for typical SOHO usage.
I get /64, so router assigns itself sub:net::8, and puts it in ddns. I can access sub:net::9, but only directly, would need to add ::9 to ddns or do some NAT from ::8 to ::9, but not sure if I can do it having only the one /64 subnet from the isp.
