Question

How to enable IPv6 addresses on a Plesk server?

Answer

Note: Applying this configuration requires administrative access. Consider contacting the Plesk administrator in case it is required.

To enable IPv6 addresses support on Plesk Server

  1. Log in to the server via SSH

  2. Create the following file /etc/sysctl.d/ipv6.conf:

    # touch /etc/sysctl.d/ipv6.conf

  3. Add the following lines into /etc/sysctl.d/ipv6.conf :

    net.ipv6.conf.all.disable_ipv6=0
    net.ipv6.conf.default.disable_ipv6=0

  4. Apply the settings from the /etc/sysctl.d/ipv6.conf via the following command:

    # sysctl -w net.ipv6.conf.default.disable_ipv6=0
    # sysctl -w net.ipv6.conf.all.disable_ipv6=0

  5. Add required IPv6 addresses in Plesk UI via Tools & Settings > IP Addresses .

  6. To enable IPv6 for Plesk UI itself create a configuration file /etc/sw-cp-server/conf.d/ipv6_ports.inc and fill it with below content:

    listen  [::]:8443 ipv6only=on ssl;
    listen  [::]:8880 ipv6only=on;

  7. Restart Plesk service:

    # service sw-cp-server restart
