環境

內網伺服器Prob1位於內網LAN1,
內網伺服器Prob2位於內網LAN2,
外網伺服器Serv1位於IP 123.123.123.123

內網節點配置

內網節點沒有inbound，只需要配置一個reverse，一個outbound（以及預設的direct），一對路由規則

  }

外網服務節點配置

外網伺服器沒有outbound，對應每個內網節點，要配置一個portal，一對inbound和一對路由規則。在這種規則配置下，對應每一個protal，會有一個專門的inbound連線，方便使用者端選擇使用不同的內網。

    ]
  }
}

建立服務

對於已經運行了v2r的機器，可以再建立一個新的服務，例如

$ more /etc/systemd/system/v2r-tunnel.service 
[Unit]
Description=V2R Tunnel Service
Documentation=https://www.v2r.com/ 
After=network.target nss-lookup.target

[Service]
Type=simple
User=root
CapabilityBoundingSet=CAP_NET_ADMIN CAP_NET_BIND_SERVICE
AmbientCapabilities=CAP_NET_ADMIN CAP_NET_BIND_SERVICE
NoNewPrivileges=true
ExecStart=/usr/bin/v2r/v2r -config /etc/v2r/config_tunnel.json
Restart=on-failure

[Install]
WantedBy=multi-user.target

通過systemctl enable 命令加入開機自啟動
