I have TrueNAS fully operational with the recommended hardware pass through in a Proxmox VM. When I installed Pihole in a proxmox LXC container it was a real challenge to get TrueNAS to access the apps and updates (was able to use SMB). I have a Verizon GS3100 & 3200 extender and Pihole is handing DHCP and DNS functions with unbound. When the setting in TrueNAS network DNS are set to 127.0.0.1 and IP Default Gateway to the Pihole I can access the files through SMB but TrueNAS cannot access the internet for apps and updates. If I change the DNS Nameserver to go to the Pihole and the IPv4 default gateway to 192.168.1.1 which is the router that is configured for the Pihole to handle DHCP and DNS it works fine. I don’t know why that is the case and want to understand and get confirmation this is OK, or recommendations to the contrary. Appreciate your feedback. On a side note, I have Windows 11 and MacOS in Proxmox VM’s and the have no issues accessing the internet.
