How to setup smart DNS on ExpressVPN?

So, you are setting up ExpressVPN on your router but it keeps giving you errors like.

Unable to connect to server. No error in logs.

When you try to connect to your ExpressVPN with an Iphone or laptop, and then use your smart DNS nameservers for DNS resolving, it gives you the same problem. In my case, I used both DynDNS (ddclient and openvpn) & Google Domains nameservers. After some research, I've tried out these solutions, and I will tell you how it works.

My configuration file contains the below. User chris-linux password saved-password logging true ca /etc/chain.crt vpn//etc/expressvpn/ExpressVPN.conf

And after I restarted my router to update, I noticed that the routing table is empty. After searching on internet for this error, I found out that this error could come because of the above configuration. So we will set it like this now.

# This is default route with our public ipaddress 10.8.1 # Route from the VPN server to the internet gw 10.2 # Set up the default dns server dns 10.3

What's wrong with this setup? # If you don't have any other option, try this first # /usr/bin/openvpn -m OpenVPN 2.3.conf --remote 192.168.0/24 --verb 4 --dev tun # Do not start the server on system startup. I'll be using the service supervisor to control it # Use either systemd or sysv init style startup scripts if you don't want to use supervisor # systemctl start expressvpn

So we are going to update the /etc/sysconfig/expressvpn file as below.
