Amazon EC2(Vyatta)からAmazon VPCに接続してみた
Amazon EC2(Vyatta)からAmazon VPCに接続してみた
「さくらのVPSにVyattaを入れて、Amazon VPCにVPN接続」を見て、EC2でもつないでみようと思い立った。
準備
AMIはVyattaのAMIを使いました。インスタンスタイプはt1.micro。
ネットワーク構成はこんな感じ。
基本的なconfigはid:iamsandmanさんのページを参考にして作成したが、EC2で動かすにあたって一部変更が必要だった。
interfaces { loopback lo { address 169.254.255.2/32 address 169.254.255.6/32 address 172.22.0.1/16 } }
- IPsecのlocal-ipに指定するアドレスはeth0のアドレスなので、起動しないとわからない。これは自動化するにはちょっと面倒。
- 接続後にルーティング情報をupdateするスクリプトを走らせる必要があるのは同様。
- VPC側のRoute Tableには以下のように戻りのgatewayを指定しておく必要がある
172.21.0.0/16 local 172.22.0.0/16 vgw-xxxxxxxx
設定の投入(追記しました)
$ configure # merge /home/vyatta/merge.txt # exit $ ./connect.sh
動作確認
