OpenVPN on LXC

適用 Ubuntu 18.04

建立 LXC 過程中需要預先關閉非特權的功能否則後續 TUN/TAP 會無法建立

apt update &&apt upgrade -y && apt install -y ca-certificates wget net-tools gnupg2
wget https://raw.githubusercontent.com/Angristan/openvpn-install/master/openvpn-install.sh -O ubuntu-22.04-lts-vpn-server.sh
chmod -v +x ubuntu-22.04-lts-vpn-server.sh
./ubuntu-22.04-lts-vpn-server.sh

建立TUN/TAP: LXC 開啟 TUN/TAP

重新設定:

/usr/local/openvpn_as/bin/ovpn-init tool

如果遇到:

LXC:Unable to create new inotify object: Too many open files 

請執行: LXC:開啟太多LXC 遇到 inotify limits 解法

# --- stop the service --- #
sudo systemctl stop openvpn@server
# --- start the service --- #
sudo systemctl start openvpn@server
# --- restart the service --- #
sudo systemctl restart openvpn@server
# --- get the service status --- #
sudo systemctl status openvpn@server

最後登入頁面下載conf之後，使用文字編輯器修改掉內網IP為外網IP，路由器開啟對應轉發Port即可
