Disable IPv6 in Linux

To avoid IPv6 leaks we need to disable IPv6 because ProtonVPN doesn’t support IPv6. To do this open the /etc/sysctl.conf config file.

sudo vim  /etc/sysctl.conf

After executing this command you need to append the following lines to the very end of sysctl.config file.

net.ipv6.conf.all.disable_ipv6 = 1 
net.ipv6.conf.default.disable_ipv6 = 1 
net.ipv6.conf.lo.disable_ipv6 = 1 
net.ipv6.conf.tun0.disable_ipv6 = 1

Save these changes.

To check these changes you need to run the following command in the Terminal.

sudo sysctl -p

To make, the Connection runs the following command.

sudo protonvpn connect

Then Select the Country to which you want to connect your IP.

Then Pick the Server location. choose the server which has a minimum load for better speed.

Then select a Protocol (TCP, UDP).

After all these steps you are now connected to the ProtonVPN.

For Disabling ProtonVPN, enter the following command:

sudo protonvpn disconnect

A virtual private network, or VPN, turns a public internet connection into a private network, offering you online privacy and anonymity. A VPN hides your internet protocol (IP) address, making your online actions almost untraceable. VPN services, in particular, allow private and encrypted connections, which provide greater anonymity than even a secured Wi-Fi hotspot.

You should utilize a virtual private network (VPN) when accessing the internet from a public area such as a coffee shop, hotel lobby, or any other facility that offers free public Wi-Fi (VPN).
