Strongswan を搭載した Ubuntu 14.04 サーバーを Microsoft Azure Gateway に接続したいと考えています。Azure とその Ubuntu サーバー間の接続を確立したいだけです。Azure で動的ゲートウェイを構成しました。
アズール:
仮想ネットワーク:
10.0.1.0/24 (仮想ネットワーク全体)
10.0.1.0/27 (VM のサブネット)
10.0.1.32/29 (ゲートウェイのサブネット)
1.1.1.1 (ゲートウェイ IP)
ローカルネットワーク:
10.0.2.15/32 (ネットワーク)
2.2.2.2 (ゲートウェイアドレス)
Strongswan を使用した Ubuntu Server 14.04:
StrongSwan: Linux strongSwan U5.1.2/K3.16.0-49-generic
通信網:
10.0.2.15 (strongswan を使用した Ubuntu サーバー)
2.2.2.2 (NAT を使用したゲートウェイ)
