dns lookup and general configuration mis config

[stred]

good morning,

After a couple of weeks of running pfsense on a standalone machine, I realised that at around 35w I needed to utilize this machine for other tasks mainly my home assistant install which was on a rpi3, so I plumped for proxmox, installed it and set about adding a pfsense vm, and then a homeassistant vm.

my setup is a optiplex 7010 with onboard nic as wan in pfsense, a secondary pcie single network card as a secondary wan (for load balancing) and a 4 port intel pcie nic as a LAN bridge, pfsense assigns dhcp to the homeassistant VM and the laptop I have connected by ethernet for maintenance, but not to proxmox.

I thought I had it setup perfectly then I went to add some addons for home assistant and I get an error which I think is DNS related.



I then checked from the homeassistant vm host terminal and can ping an ip but not a namespace



I then tried pinging from the proxmox console in putty and the same scenario



below is my /etc/network/interfaces

auto lo
iface lo inet loopback

iface eno1 inet manual

iface enp1s0f0 inet manual

iface enp1s0f1 inet manual

iface enp1s0f2 inet manual

iface enp1s0f3 inet manual

iface enp3s0 inet manual

auto vmbr0
iface vmbr0 inet manual
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0
#WAN

auto vmbr1
iface vmbr1 inet manual
        bridge-ports enp3s0
        bridge-stp off
        bridge-fd 0
#WAN4G

auto vmbr2
iface vmbr2 inet static
        address 192.168.1.2/24
        gateway 192.168.1.3
        bridge-ports enp1s0f0 enp1s0f1 enp1s0f2 enp1s0f3
        bridge-stp off
        bridge-fd 0
#LAN

I've checked the DNS is 8.8.8.8 in proxmox gui, i'm sort of stumped not knowing where i've gone wrong.

kindest regards

Can pfsense resolve DNS names?

 

[stred]

yes, my laptop connected by ethernet to the pfsense lan can browse websites as normal and a ping test confirms this from pfsense gui.



I also made some changes to try and nail the mistakes, by taking VMBR0(maintenance port) off the pfsense LAN and have connected a cable between eno1 (VMBR0) and the pfsense LAN and can now ping name spaces correctly from within the proxmox gui.

Can pfsense resolve DNS names

 

[apoc]

ok. Does this mean now everything is working?

It seems the home assistant problem was due to a bad image and i'm currently in the process of creating a new vm for that.

I would like to move the maintenance port back to the pfsense LAN eventually to remove the need for the cable and gain the two ports back, i'm hoping and confident this is possible but will tackle that later this coming week
