Details about my system:
I run pi-hole on a NAS server using TRUENAS scale OS, the pi-hole application has been installed inside a docker using the applicaion list provided by the TRUENAS catalog. I have found on this forums several topics that helped me to setup and make it work, pi-hole act
but...
The issue I am facing:
I cannot keep the IPV6 support (SLAAC+RA) enabled, the setting is always overwritten and disabled when I restart the docker. If I change setupVars.conf manually, the fille is overwritten at restart too. And I haven't found a way to add this environment variable to the docker itself.
Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:
pihole -d
or do it through the Web interface:
Tools > Generate Debug Log
You could set Pi-hole's corresponding optional environment variable DHCP_IPv6
for your Pi-hole container.
But commonly, your router would already provide stateless DHCPv6 support.
What's your purpose for enabling Pi-hole's IPV6 support (SLAAC+RA)?
If I don't enable this the PC with Windows 11 lose internet access after some time
If I change the setting inside the setupVars.conf, the file is overwritten with a new where this variable is blank.
I am not sure if the ISP router is doing its job but I can run Wireshark again to control this
I ran it w/o the IPV6 support (SLAAC+RA) for a time and after one or two days the DNS answer is wrong with IPV6:
Result with IPV6 SLAAC+RA = OFF
if I enable IPV6 support (SLAAC+RA) the answer is correct again
Result with IPV6 SLAAC+RA = ON
Might be the ISP routeur but I expressly setup inside the ISP routeur the pihole as primary IPV6 DNS serveur
So, if that PV6 SLAAC+RA could stay enable and not overwritten at every restart, that would solve my issue
no answer
maybe I should use another software?
Well, did you try that environment variable in the last 5 days yet?
I was doing it fully wrong. After some more test I could finally set this environment variable to the right value
Everything works fine, thank you for your precious help!
