I have an issue configure a PFSense firewal on an ESXi with an IP Failover.
I have followed all these points:
- Create one /56 block on online.net console
- Create 2 x /64 subnets from it
- On WAN interface, configure the DUID from the /56 block and add one ipv6 from the first /64 (with this howto
- On LAN interface, add one ipv6 from the second /64 with IPv6 Configuration Type = Static IPV6
- On DHCPv6 nothing (unused)
- On Router Advertisements , choose “ Unmanaged ” and set DNS servers (google : 2001:4860:4860::8844 & 2001:4860:4860::8888)
And the result I amm blocked/nulrouted systematically, because of a DHCPv6 flood !!!
Is there somebody who can help me ?
Thanks in advance…
