After you get connected to the Trust.Zone VPN your IPv4 IP address will change, but your IPv6 address will remain the same.
This is not a problem in case your ISP does NOT support IPv6, but in case it does, your IPv6 address may leak.
The best way to prevent IPv6 from leaking we recommend to disable IPv6 in your linux distro. Here is how you can do that.
To check if IPv6 is already disabled please run the following command:
If command returns 1, then IPv6 is already disabled and you can skip steps below. In case return value is 0, please follow the instructions below:
Run the following commands to disable IPv6 for the current Ubuntu session:
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
To disable IPv6 during Ubuntu startup we recommend to edit GRUB loader settings.
Please open /etc/default/grub file in your favorite text editor. In our example we will use nano editor.
sudo nano /etc/default/grub
Locate the following lines
GRUB_CMDLINE_LINUX="find_preseed=/preseed.cfg auto noprompt priority=critical locale=en_US"
Add the parameter ipv6.disable=1 to the end of the values of the GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX parameters (inside quotes):
After editing, you should get the following lines:
GRUB_CMDLINE_LINUX="find_preseed=/preseed.cfg auto noprompt priority=critical locale=en_US ipv6.disable=1"
Now you can save the file and exit the editor. In case you use nano, you need to press Ctrl-O to write changes and press Enter to confirm file write. Then you can press Ctrl-X to exit the editor.
Run the following command to apply the GRUB changes:
The command will return the following output:
user@ubuntu:~$ sudo update-grub
