Local DNS issue - Peplink Balance 20 and One

Hi all,

I have a problem about local DNS issue on Peplink Balance 20 and One.
I set a Outbound policy if match “google.com” will pass through WAN1, others traffic will pass through WAN2.
if my laptop set public DNS(e.g., traceroute google.com and www.google.com will be pass through WAN1.
if my laptop set local DNS(the same IP subnet with the laptop), www.google.com must be pass through WAN2, google.com will pass through WAN1, but sometimes will pass through WAN1.

any idea?


Please ensure you use Balance’s LAN IP as laptop’s DNS server. If internal DNS server is preferred, please ensure no caching for google.com in internal DNS server.
