2 DNS, but only use 1 for phonesystem

TVV

Hi,

I have two WANs connected on my Sophos XG SFOS 18.5.1. The DNS is configured with "Obtain DNS from PPPoE".

My Problem now is, that my PhoneSystem is using DNS from the Sophos.

But it may only use the DNS from WAN2 and not from WAN1.

How can I configured it, that the phonesystem only uses DNS from WAN2?

Thanks!

Best Regards Thomas

    i would try one of these 2 options
    - within firewall: don't use "Obtain DNS from PPPoE" and configure multiple DNS-Servers providing the information your phone-system need
    - configure a usable external DNS within your Phone-server and allow access via Firewall-rule
