I am adding DHCP and DNS on eth3 in home network LAN. I am confuse about DNS settings. More, than I expected.

  1. set service dns forwarding cache-size '0'

why in quick start example? Quick Start — VyOS 1.3.x (equuleus) documentation
Is it recommended settings for home network?

  1. set service dns forwarding dhcp <interface>

Interfaces whose DHCP client nameservers to forward requests to.

What does it mean? Should I set this? What is the effect of this setting?
Should I set this to:
set service dns forwarding dhcp bond0 so to the WAN? ?

  1. set service dns forwarding name-server <address>

Send all DNS queries to the IPv4/IPv6 DNS server specified under . You can configure multiple nameservers here.

As I understand I can set there DNS like 1.1.1.1 from cloud flare or 8.8.8.8 from google. In quick start this is not set. What is happening then? It use DNS from internet provider? But if I set some servers here, then it doesn’t use DNS from internet provider, but only and only what I define here?

  1. set service dns forwarding allow-from <network>

Should I set this? I want to make this DNS only for my home network. Not public.

  1. set service dns forwarding listen-address <address>

Is it just IP for DNS server? So in general the same as DHCP, so 192.168.0.1.

  1. set service dns forwarding source-address <address>

Can it be useful for home network?

  1. Can you paste show service dns on your VyOS for your home network?
