Hi..
i just have unifi 100m few week ago, i use pfsense connect to ONU (Fiberhome HG6240A) via PPPOE, internet is fine, but i have some problem with IPv6 .
when i boot up pfsense, it get a IP from TM and the DHCP6 also working, but after days ( i not sure how long .. seem over 24 hours) the DHCP6 will go "offline" , just now i found out the DHCP6 is offline , so i restart the ONU and pfsense , but this time it won't work (before this i also have this problem but fix it after i restart the ONU and pfsense), i get a new IP address from TM , but DHCP6 still offline ...
i am not very good at networking.
any pfsense sifu can help ?

LAN:


this is the status:



this is my DNS setting:



and this is the Log with the error:



is my setting correct?

thanks.
