Use Vyos (1.3.4) Default gateway address (10.1.120.1) as DNS-server for vif120 (DNS forwarding)

General questions

Hi
Have a test network with following:

vif 120
address 10.1.120.1/24
description VLAN120

I have setup
system name-server 8.8.8.8
system name-server 1.1.1.1

dns forwarding allow-from 10.1.120.0/24
dns forwarding listen-address 10.1.120.1
dns forwarding system

service {
dhcp-server {
shared-network-name VLAN120 {
subnet 10.1.120.0/24 {
range 0 {
start 10.1.120.100
stop 10.1.120.200

But when I use client with DHCP on VLAN120 i only get ip address, no DNS address.

What am I missing/doing wrong?

You didn’t set name-server for shared-network-name

If you want to use the forwarder in VyOS then yes it should be 10.1.120.1.

But personally I would generally avoid using forwarder and instead just use NAT towards Internet if needed.

A better option if you still want to use forwarder is to install PI-Hole or similar in a container in your VyOS to get better statistics and filtering of DNS queries passing by.
