YAMAHA1200を使うと簡単にIPsecによる拠点間VPNを作れます。
オフィスのVPNは拠点間で１つのファイルサーバを共有するのによく使いますが、最近ではクラウドとVPN接続してオフィスのネットワークを拡張するといったことも流行です。
よくする手順
- ウィザードでLAN1のプライベートネットワーク設定
- LAN2のWANの設定
PPPoEならプロバイダ接続の設定を行う - そりゃやっぱり ぜったい がっちり 固定IPの方がイイ！
固定IPの確認 or ネットボランチ設定
固定IP ･･･そのままでよし!
PPPoE ･･･ネットボランチでホスト名の設定必要
※ネットワーク型プロバイダ接続型で固定IPでない契約の場合、
拠点間VPN(IPsec)はRTX1200はネットボランチ非対応？RTX1210はいけた！ - L2TP(VPN)でanonymousチャンネルの作成
これでSSHみたいに遠隔地のルータを操作出来ます。 - 機器を出荷します！！
- 出荷先の担当者にONUと機器のWANを接続して貰います。
これでL2TPでリモートから設定できるようになりました。
PPPoEの場合はここでネットボランチ設定を行います。 - 拠点間VPNの設定
L2TPでのVPN経由でGUIから拠点間VPN(IPsec)設定するのが楽
よくある設定でRTX1200で拠点間VPN組むならこの手順が安定しています。

GUIでIPsecを設定する
A拠点からB拠点へIPsecの設定を行います。
B拠点のIPsecを設定しているインターフェイスにB拠点の静的経路(192.168.11.10/24)の設定を追加します。
また、B拠点のルータでも同様にA拠点のIPsec設定を行います。A拠点とB拠点の設定が終わったわけです。そうするとステータスがUPになります。
お疲れ様です。
