Openvpn and unbound combined break dig command


  • when doing DNS lookup against remote unbound server over OpenVPN connection
    • results not coming back, or say "reply from unexpected source" 
    • ping and ssh work fine


  • fix unbound.conf 
    • "interface" parameter -> local ip instead of "0.0.0.0"
    • replies will have the local ip and not the OpenVPN ip now

Sample reply when still broken:

;; reply from unexpected source: 192.168.30.1#53, expected 172.30.1.54#53
