IPv6 Forwarding can be disabled via the set interface openvpn vtunx ipv6 disable-forwarding command, but note that IPv6 traffic can still be terminated on this interface.

IPv6 configuration can be totally disabled via the set interface openvpn vtunx ipv6 disable command.

Use the set form of this command to disable IPv6 on this interface.

Use the delete form of this command to enable IPv6 on this interface.

Use the show form of this command to display the current IPv6 configuration on this interface.
