web-001 on the same hypervisor has correct IPv6 support, we can do the same for Hervil with the /56 trick and the hello trick:

We can use this OVH IP, it's stable enough now.

DNS records have been updated:

So, to get routing back:

Note we've still a case for deploying poudriere itself, but that can be tracked in a new task, T2039.

Mumble isn't currently in scope.

T169 / D3168 seems to work

Worked before (dhclient + routes), but on boot:

• we've a correct fe80 address
• no dhclient, but /usr/local/etc/rc.d/dhclient6 start does NOT complain dhclient6_enable="YES" is missing
• when dhclient is started, our correct prefix is returned
• no static IP assignment in current state (missing from /etc/netif/igb0_ipv6)
• we can add manually IP in our prefix
• routing is missing and can't be easily figured (the expectation was dhclient would take care of that)

Taking it as we've issues with the /128 one and I'd prefer to fix the /56 config than the /128 one.

Libera accepts connections in IPv4 and with SASL we can connect from Scaleway network.

Meanwhile, we configured correctly GRE interface and IPv6 tunnel separately,
so at next Dwellers reboot, we need to state what works

Does Vikidia still needs this?
