Disable IPv6

Disabling IPv6 on Proxmox VE

In some homelab environments, you may want to disable IPv6 to simplify your network configuration or for compatibility reasons. This guide will show you how to disable IPv6 on your Proxmox VE host.

Steps to Disable IPv6

  1. Log in to the Proxmox VE Shell: Access the Proxmox VE host's shell either through the web UI or by connecting directly via SSH.

  2. Disable IPv6: Run the following commands to disable IPv6:

echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf

These commands append two lines to the `/etc/sysctl.conf` file, which configures kernel parameters.
*   `net.ipv6.conf.all.disable_ipv6 = 1`: Disables IPv6 for all network interfaces.
*   `net.ipv6.conf.default.disable_ipv6 = 1`: Disables IPv6 for any new network interfaces that are created.
  1. Apply the Changes: To apply the changes without rebooting, run the following command:
sysctl -p

This command reloads the kernel parameters from the `/etc/sysctl.conf` file.

Verify that IPv6 is Disabled

To verify that IPv6 has been disabled, you can run the following command:

ip a | grep "inet6"

If the command returns no output, then IPv6 has been successfully disabled.

Next Steps

With the Proxmox VE host configured, you can now proceed to set up your active directory.
