Access to Google DNS servers via OpenVPN

[Andrey_3]

Hello!

I have Asus RT-AC87U and Asuswrt-Merlin firmware 380.57.
I need to access to Google DNS servers 8.8.8.8 and 8.8.4.4 via OpenVPN tunnel.

I have this WAN DNS setting:

and these OpenVPN client policy routing rules:

Only one computer (192.168.0.3) in LAN (192.168.0.0/24) gets access to internet via VPN.
All other computers in the LAN gets direct access to internet via ISP.
DNS server for all computers in the LAN is set to 192.168.0.1 (IP of RT-AC87U).

This configuration is working, but I can't get correct traceroute 8.8.8.8 and 8.8.4.4 on router and on LAN computer 192.168.0.5:

traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 38 byte packets

7  *  *  *
8  google-public-dns-a.google.com (8.8.8.8)  14.875 ms  15.036 ms  14.795 ms

Is this configuration "DNS via VPN" is correct?

Thank you.
