| Take note of the IPv6 prefix assigned then disable IPv6 LAN in the Fastgate (Avanzate->then disable "IPV6 su LAN"). | |
| Commands: | |
| /interface 6to4 | |

| /ipv6 settings | |

| Check also DNS servers and other stuff. | |
| Note: | |
| -) 192.168.2.1 is the LAN IP of the Mikrotik interface connected to the Fastgate, also in DMZ. | |
| -) Use RouterOS stable (version 6.48.1 works). Beta 7.1beta5 can't maintain a stable IPv6 interface. | |
| -) XXXX:YYYY needs to be changed to the prefix available in the Fastgate (Prefisso IPV6 (6RD)). | |
| -) 512 in 2001:b07:XXXX:YYYY::512/64 is a random value. | |
| -) 81.208.50.214 could change by geographic location. |
