Add IP allowlist and diagnostic PowerShell scripts

Added allowed_ips_updated.txt containing updated allowed IPs and configuration examples. Introduced check_ip.ps1 and check_ip_fixed.ps1 for checking current IPs against the allowlist and performing connectivity tests, with the fixed version improving external IP detection. Added diagnose_127.ps1 to help diagnose and resolve issues related to services binding to 127.0.0.1.

## 完整IP清單一行一個
114.33.18.13
125.229.65.83
60.248.164.91
220.132.236.89

219.87.170.253
125.228.50.228
114.40.30.219
## 問題解決方案
### 如果顯示 127.0.0.1 的問題:
1. **檢查應用程式綁定設定**
- 確保應用程式綁定到 `0.0.0.0` 而不是 `127.0.0.1`
- 檢查配置文件中的 bind 設定
2. **常見的解決方法**
```bash
# 如果使用 Node.js
app.listen(3000, '0.0.0.0', () => {
console.log('Server running on 0.0.0.0:3000');
});
# 如果使用 Python Flask
app.run(host='0.0.0.0', port=5000)
# 如果使用 Apache
Listen 0.0.0.0:80
# 如果使用 Nginx
listen 80;
server_name _;
```
3. **檢查防火牆設定**
- 確保防火牆允許外部連接
- 檢查端口是否開放
4. **網路配置檢查**
- 確認網路介面卡設定正確
- 檢查路由表設定
## 防火牆規則格式(更新版)
### Windows 防火牆 (PowerShell)
```powershell
# 允許所有IP包含當前IP
$allowedIPs = @(
"114.33.18.13",
"125.229.65.83",
"60.248.164.91",
"220.132.236.89",
"211.72.69.222",
"219.87.170.253",
"125.228.50.228",
"114.40.30.219" # 當前IP
)
foreach ($ip in $allowedIPs) {
New-NetFirewallRule -DisplayName "允許IP: $ip" -Direction Inbound -RemoteAddress $ip -Action Allow
}
```
### Linux iptables
```bash
# 允許所有IP包含當前IP
iptables -A INPUT -s 114.33.18.13 -j ACCEPT
iptables -A INPUT -s 125.229.65.83 -j ACCEPT
iptables -A INPUT -s 60.248.164.91 -j ACCEPT
iptables -A INPUT -s 220.132.236.89 -j ACCEPT
iptables -A INPUT -s 211.72.69.222 -j ACCEPT
iptables -A INPUT -s 219.87.170.253 -j ACCEPT
iptables -A INPUT -s 125.228.50.228 -j ACCEPT
iptables -A INPUT -s 114.40.30.219 -j ACCEPT # 當前IP
```
## 程式碼格式(更新版)
### Python 列表
```python
ALLOWED_IPS = [
"114.33.18.13", # 岡山 Hinet
"125.229.65.83", # 汐止
"60.248.164.91", # 汐止
"220.132.236.89", # 新竹
"211.72.69.222", # 新竹
"219.87.170.253", # 璟茂
"125.228.50.228", # 璟茂
"114.40.30.219" # 當前IP
]
```
### JavaScript 陣列
```javascript
const allowedIPs = [
"114.33.18.13", // 岡山 Hinet
"125.229.65.83", // 汐止
"60.248.164.91", // 汐止
"220.132.236.89", // 新竹
"211.72.69.222", // 新竹
"219.87.170.253", // 璟茂
"125.228.50.228", // 璟茂
"114.40.30.219" // 當前IP
];
```
## 驗證腳本
### 檢查當前IP是否在允許清單中
```powershell
# PowerShell 驗證腳本
$currentIP = (Invoke-WebRequest -Uri "https://ifconfig.me/ip" -UseBasicParsing).Content.Trim()
$allowedIPs = @("114.33.18.13", "125.229.65.83", "60.248.164.91", "220.132.236.89", "211.72.69.222", "219.87.170.253", "125.228.50.228", "114.40.30.219")
if ($allowedIPs -contains $currentIP) {
Write-Host "✅ 當前IP ($currentIP) 在允許清單中" -ForegroundColor Green
} else {
Write-Host "❌ 當前IP ($currentIP) 不在允許清單中" -ForegroundColor Red
}
```
## 安全建議
1. **定期更新**建議定期檢查和更新IP地址清單
2. **記錄存取**記錄所有IP的存取日誌
3. **備用方案**:考慮設定備用的存取方式
4. **監控異常**監控未授權IP的存取嘗試
5. **網路分段**考慮使用VPN或專用網路
6. **IP變更通知**設定IP變更時的即時通知機制
