Secondary DNS Settings Not Working on IKEv2 VPN Connections

I have an odd thing happening with my IKEv2 VPN clients. Under the configuration of the IKEv2 VPN, I'm telling the clients to use the DNS/WINS settings.

In my Policy Manager, I have two DNS servers listed in the DNS/WINS area.

But when my IKEv2 VPN clients connect, they all see the same secondary DNS server, which is some IP that resolves to an ISP in Japan. Any idea why the second DNS server isn't being passed to the clients and where it's getting the secondary DNS server setting in the first place?

    Is your Firebox device External port configured to use DHCP?

    Hi @BPL
    If you haven't already done so, I would suggest opening a support case. I would not expect that behavior, but it's difficult to diagnose without access to the firewall.
