Does anyone here kindly have a basic config they could share/DM getting IPv6 working with a mikrotik router?

I switched from PPPoE to IPoE/DHCP back in February, setup DHCPv6 via PD and had it working fine, but since rebooting from the outage earlier this week I just can't obtain a prefix, its stuck in 'searching' with what I am sure was the original config. (DHCPv6 also worked over PPP back then too)
Tried blowing it all away with the most basic of settings, single no-vlan network, ensuring a firewall rule for udp on 546 from src fe80::/10 but still just stuck 'searching'.

I am only configured for IPoE (all PPP config deleted) and the portal shows connection by DHCP, with both my /32 and /56 listed.

I know many of you have moved on from RouterOS but thought someone here might still be running one.

A simple reboot fixed it instantly with my existing settings.

So ill just guess the power cycle earlier this week didn't work, perhaps the network wasn't quite fully restored.
I don't have any fancy firewall rules other than the default.

So something within RouterOS must timeout, or something needs to happen in order with the requirement of a reboot. Next time ill down the WAN port and bring it up to see what result there is.

I should follow my own advice I give to everyone else, have you rebooted it?

I have done it the following way:

IPv6 settings:

This must be set to accept route advertisements = yes and IPv6 Forwarding ticked.

IPv6 client:

Set this to your WAN interface port (in my case ether1) and tick prefix. Create a custom pool name.
Pool Prefix Length at 64 but the Prefix Hint at 56. Also note the checkboxes.

ND settings:

It's important to advertise the MAC address.

Then for the ipv6 address pool (if you care about your LAN devices getting IPv6 addresses):

Create a new IPv6 address, select from Pool: and type the same pool name you defined in the IPv6 client screen.

Set the interface to bridge and tick advertise.

** After this reboot the router **
