However, there are cases where disabling IPv6 becomes necessary. For instance, like simplifying network management or addressing specific issues.

<div id="bkmrk--3">  
</div>Today, we are going to take a look at how to disable IPv6 on pfSense.

<div id="bkmrk--4">  
</div>1. 1. First, we have to head to System &gt; Advanced &gt; Networking. <div>  
        </div>
    2. Then, we have to uncheck the “Allow IPv6” checkbox. <div>  
        </div>
    3. Next, it is time to turn on Logging for PFsense Default Blocks. We can do this by heading to Rules under Firewalls. <div>  
        </div>
    4. Now, click the icon to view the logs in the top right corner. <div>  
        </div>
    5. Then, click Settings and check the boxes next to “Log firewall default blocks.” <div>  
        </div>This will give us access to IPv6 traffic in our logs.
        
        <div>  
        </div>
    6. Next, we have to make sure DHCPv6 Relay is disabled. We do this by heading to Services &gt; DHCPv6 Relay and unchecking “Enable.” <div>  
        </div>
    7. Then, save and apply the settings. <div>  
        </div>
    8. Furthermore, we have to disable IPv6 on each Interface individually. <div>  
        </div>
        - First, head to Interfaces and review the list of interfaces on the firewall. <div>  
            </div>
        - Then, start with the WAN interface and click it. <div>  
            </div>
        - After that, we have to set the configuration type for each interface to “None.” <div>  
            </div>
        - Next, save and apply our changes. <div>  
            </div>
        - We have to repeat this process for all other interfaces. <div>  
            </div>
    9. Finally, head to Routing under System and set “Default gateway IPv6” to “none.” Then click Save. <div>  
        </div>
    10. Additionally, we can create firewall rules to block IPv6 to help identify potential misconfigurations or issues. This step is optional but can be useful for monitoring.

</div>After the above steps, we will no longer see IPv6 traffic in our logs.
