giwa / CentOS6-L2TP-IPsec.md
Created October 21, 2020 04:14 — forked from CLCL/CentOS6-L2TP-IPsec.md
L2TP/IPsec（AndroidやiPhoneからのVPN接続）を経路を用意すべくVPSにL2TP/IPsecサーバを設置するとき、ネットにある情報だとなかなかつながらないから、標準環境としてAWSのCentOS 6.3 x86_64 Release Media(ami-3fe8603e)の起動直後から最短距離で設定する方法をまとめた。

CentOS 6でとにかくL2TP/IPsecサーバ

  • AWSでEC2のインスタンスを借りる
  • 今回は東京リージョンのCentOS 6.3 x86_64 Release MediaのAIM(ami-3fe8603e)でインスタンスを建てる
  • Security Group: L2TP/IPsec（Inbound 22/TCP: SSH, 500/UDP: ISAKMP, 1701/UDP: L2TP, 4500/UDP: IPSec NAT Traversal）を許可
  • ec2-54-249-173-214.ap-northeast-1.compute.amazonaws.com（グローバルIPアドレス：54.249.173.214）にrootでログイン
