Using Linux has become more and more frequent with more and more users getting accustomed with the Linux environment. Luckily, the below steps are provided as to how to disable IPv6 - via terminal command line parameters.
Note: Make sure that when opening the Terminal window, the Linux account has Administrator privileges.
Step 1: Once Terminal is opened, the following command line is needed: sudo nano /etc/sysctl.conf
You may be required to input the sudo password for the Administrator account.
Step 2: With the sysctl.conf opened, scroll to the bottom of the document and - one by one - add the following parameters:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
To save the changes, press Ctrl and X to Exit(Save).
Step 3: The following parameter is needed to verify the settings implemented earlier: sudo sysctl -p
Step 4: Running the following line will display if IPv6 is disabled:
Resulting with: 1 - it means that IPv6 is Disabled
Resulting with: 0 - it means that IPv6 is still Enabled
Q: I am getting the result "0". Does it mean that that IPv6 is still Enabled ?
A: Ensuring maximum privacy is our top concern and to make sure that IPv6 is Disabled, the recommendation is to make sure that redoing all the steps carefully is equally important but Support will stand by for any difficulties that are encountered.
Q: Why does Support ask me to disable IPv6 ?
A: Support may request that IPv6 is disabled from your end as this step is imperative that the VPN tunnel is working optimally and nothing will hinder the traffic even if only IPv4 is used.
Q: My ISP provides only IPv6 !
A: No worries ! For the best approach, please get in touch with the Support Team at the below addresses and the best action plan will be put up so that your privacy and anonymity is ensured.
Q: I disabled IPv6 but my VPN still does not work. What do I do now ?
A: Disabling IPv6 is just one of the steps that can be used for troubleshooting and for a more extensive investigation, please get in touch with the Support Team.
