YAMAHA RTX1200 IPsecで拠点間VPN

 

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

1. ウィザードでLAN1のプライベートネットワーク設定
2. LAN2のWANの設定
   PPPoEならプロバイダ接続の設定を行う
3. 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)は難しい･･･私は知らない。
4. 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。
5. 機器を出荷します！！
6. 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。
7. 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。
