vyatta で Amazon VPC に接続
最近、Amazon VPC がどんどん機能強化されて目を見張るばかりです。
Vyatta を VPC の Customer Gataway として使えるかどうかテストした結果をまとめておきます。
結果
ネットワーク構成
10.255.254.0/23 = VPC側の CIDR
10.255.252.0/23 = 顧客側の LANセグメント
169.254.255.0/30 = IPsec tunnel #1
.1 = VPN Gateway
.2 = Customer Gateway
169.254.255.4/30 = IPsec tunnel #2
.5 = VPN Gateway
.6 = Customer Gateway
1.2.3.4 = Customer Gateway
72.21.209.225 = VPN Gateway #1
72.21.209.193 = VPN Gateway #2EC2
