DNS resolver (unbound) and multi-WAN

  • Hello guys,
    moving from dnsmasq to unbound still gives me headache. So I hope you can help me. My pfsense router has two physical NICs, LAN and WAN. In addition to the WAN interface I have established two openVPN tunnel to my VPN provider. So I consider this as a multi-WAN setup, right?
    According to https://doc.pfsense.org/index.php/Unbound_DNS_Resolver I supposed to have forwarding mode enabled.
    Also I have defined my VPN providers DNS server under System > General and do not want to query root servers.
