The port and protocol your server uses to communicate.The public IP address of the VPN server you connect to.In order to setup a VPN kill switch in UFW, you need three pieces of information: Now that IPv6 has been disabled system-wide, you can move on to collecting the information you need to set up the VPN kill switch with UFW. If you’ve already enabled UFW prior to starting this project, you’ll need to disable it with the following command: sudo ufw disable Scroll through until you find the setting for IPv6 rules, and change it to read: IPV6=no To turn off IPv6 in UFW, open the file /etc/default/ufw for editing using this command: sudo nano /etc/default/ufw Doing so will reduce clutter in your ruleset and might save you some confusion later on. Even through the protocol has been disabled at the operating system level, UFW stubbornly insists on adding IPv6 rules until it’s been told to stop. Next, you’ll want to stop UFW from automatically creating IPv6 firewall rules. If your system displays a 1 as output, IPv6 has been disabled successfully. In this case, use the following command to make sure IPv6 is disabled at the operating system level: cat /proc/sys/net/ipv6/conf/all/disable_ipv6 You can confirm the changes were applied successfully by taking a look at files in the /proc which contain information about your system. Save your changes with Ctrl+X, Y and force the system to reload nf and apply your changes using the command: sudo sysctl -p Scroll through the file until you see an entry for and add the following three lines to the end of the configuration file: .disable_ipv6=1 .disable_ipv6=1 .disable_ipv6=1 To get started, open /etc/nf for editing with the following console command: sudo nano /etc/nf /etc/default/ufw to stop UFW from automatically creating IPv6 rules.In Ubuntu, that means you’ll need to edit the following files: You’ll need to disable IPv6 for both the operating system and UFW to be sure that your VPN provider won’t passthrough IPv6 traffic unencrypted. This step is optional, and you can skip it if necessary. I think it’s a good idea to disable IPv6 entirely unless you’re positive your provider supports it. Many VPN providers still don’t have adequate IPv6 support, which can cause data leaks and other issues. Once the commands have finished executing, you’re ready to get started setting up a VPN kill switch with UFW.

Use the following commands to update your operating system and installed software: sudo apt update sudo apt upgrade -y As long as you’re using a Debian-based Linux operating system, the steps will be identical. I’ll be using Ubuntu 18 LTS for this guide. Before you beginīefore you get started, it’s a good idea to make sure your system is up to date. If you’ve ever struggled with Linux networking but still need a secure and user friendly firewall, I recommend UFW. UFW makes it much simpler to build a useful ruleset, especially if you’re not a Linux power user who knows iptables by heart. iptables is a powerful tool, but it’s not very easy to use. UFW is a set of scripts that act as a wrapper to the Linux iptables firewall. If you’ve ever kicked yourself for browsing while your VPN was down without even noticing, creating a VPN kill switch with UFW is a pretty easy fix. They’re completely automated, with the kill switch only kicking in when there’s a problem with your secure connection. A VPN kill switch is a set of firewall rules that will stop all internet traffic when your VPN isn’t connected.
