 ### ネットワーク設定の変更

 #### 失敗編の反省から
 Open-WRTは、無線LANブロードバンドルーターをメインターゲットとしたOSであるため、ネットワーク設定もデフォルトではルーター用に都合のよい設定になっているみたいだ。
-ReadyNAS Duo v2はネットワークにLANポート一基のみ搭載したシンプルなNASであるため、Bridgeなどのややこしいネットワーク構成はいらない。
+ReadyNAS Duo v2はネットワークにLANポート一基のみ搭載したシンプルなNASであるため、Bridgeなどのややこしいネットワーク構成はいらない。（ReadyNASは、完全にローカル向けで、外部インターネットに公開するつもりはない）
 そこで、まず最初にネットワーク設定をシンプルなものに変更した。
 同時にIPアドレスをDHCPでもらってくるのではなく、静的IP（192.168.10.2）となるようにした。
 ついでにDNSもここで我が家のブロードバンドルーター（192.168.10.1）に設定した。

+OpenWRTインストール直後のネットワークの状態と/etc/config/networkファイル

 ### Web設定 LuCI のインストール
+ネットワーク越しにSSHできるようになったから、もうUSB-シリアル変換ケーブルは必要ない。
+TeraTermでもRloginでもWLS2のUbuntuからでも何でもよいのでSSHで ReadyNAS (192.168.10.2) に接続
 ネットワーク設定をちゃんとしたので、今回はopkgコマンドがIPv6で困った、なんてことはなく、すんなり入った。
