I have a new MikroTik RouterBoard 951G (updated to RouterOS v6.47.8). It replaces an 8 y/old RB715G-2HnD that died.
I have been using IPv6 for over 10 years, same ISP. I am running Debian 10 on my main (UTP wired) PC.
I want to set up static addresses (works) but I cannot get to the outside world, I suspect that I have not got a good default route.
I suspect that wanting to do this is quite common - but there is nothing (obvious) that takes me through it. Can someone please point me to something that I can follow.
Trying DHCP does not set up IPv6 - the documentation on how to do so is not helpful.
Firstly, as the IPv6 package is disabled by default it is wise to enable it, reboot, and then reset the configuration to include the IPv6 firewall rules.
Configuration varies depending on how your ISP delivers IPv6 - some are static only (my ISP doesn’t do native IPv6 so I have a 6to4 tunnel, static /64 WAN, and routed /64 & /48 subnets for LAN), some provide native IPv6 over PPPoE, some provide WAN address and/or address prefix via DHCP. You also need a default global unicast default route:
/ipv6 route
add distance=1 dst-address=2000::/3 gateway=
