ファイヤーウォールの設定
firewalld側で設定するのでとりあえず0を指定

FIREWALLING

Please choose the firewall rules to use. Note that these rules are
very basic. You are strongly encouraged to use a more sophisticated
firewall setup; however, these will provide basic security. If you
are running any servers on your machine, you must choose 'NONE' and
set up firewalling yourself. Otherwise, the firewall rules will deny
access to all standard servers like Web, e-mail, ftp, etc. If you
are using SSH, the rules will block outgoing SSH connections which
allocate a privileged source port.

The firewall choices are:
0 - NONE: This script will not set any firewall rules. You are responsible
for ensuring the security of your machine. You are STRONGLY
recommended to use some kind of firewall rules.
1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation
2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway
for a LAN
Choose a type of firewall (0-2): 0

CentOS7.4でPPPoE接続 NetworkManager編

パッケージインストール

NetworkManager-pppを入れる

# yum -y install NetworkManager-ppp

1	# yum -y install NetworkManager-ppp

rp-pppoeは不要みたい。

第14章ネットワーク PPP サポートの別パッケージへの移動

今回の更新では Point-to-Point Protocol (PPP) サポートが別のオプションの NetworkManager-ppp パッケージに移動されました。そのため、NetworkManager の依存関係チェーンが少なくなり、インストールするパッケージの数を減らすことができます。
PPP 設定を設定するには、NetworkManager-ppp パッケージがインストールされていることを確認する必要があります (BZ#1404598)。
