Network Wide Pihole on Proxmox

[mayan57476]

Expected Behaviour:

Set dns server on Proxmox container that Pi-Hole is running on as a valid third party dns, a working instance of unbound or itself and pihole should have access to the internet

Actual Behaviour:

-Have fully functional debian 12 or ubuntu 24 with a working static IP adress and pihole installed, has access to internet, and pihole web interface is accessible and says its online
-Set pihole as dns server in router settings, Pi-Hole and the container its on immediately lose internet(still accessible locally) despite it not being supposed to use the gateway's default DNS(to my knowledge, i have tried numerous things over two days, including using nmtui, which is pretty hard to screw up)

Debug Token:

Debug Token not included because as stated, the ccontainer no longer has internet (even if the router dns settings are returned to default). I will set up pihole from new and send the debug right before the critical step, if need be.

Even if the container has no internet, you can create the debug log with pihole -d and then copy the file /var/log/pihole/pihole_debug.log to one side to save it, get Pi-hole back online and then send that debug log to the server with

sudo cat pihole_debug.log | pihole tricorder

and mention the token URL in here, along with an explanation of what has been uploaded so it can be made sense of.
