### Route Configurations Below
route 192.168.254.0 255.255.255.0

### Push Configurations Below
push "dhcp-option DNS 1.1.1.1"
push "dhcp-option DNS 1.0.0.1"
push "comp-lzo no"

I have this configuration but every DNS leak test shows me a DNS leak alert.

Please show me how I can enable security for DNS or fix this problem for different openvpn clients (macos, linux).
