如何禁止国外IP访问企业网站？3种有效方法对比
作者：悦然WordPress建站
网站安全形势严峻：当前网络环境中，所有网站都面临被攻击风险，而大多数攻击IP来自国外。如果您的企业网站仅面向国内用户，禁止国外IP访问是有效的安全措施。
Website Security Situation: In the current network environment, all websites face the risk of being attacked, with most attack IPs coming from abroad. If your business website only targets domestic users, blocking foreign IP access is an effective security measure.
方法一：使用阿里云CDN禁止国外访问
Method 1: Using Alibaba Cloud CDN to Block Foreign Access
如果网站使用阿里云CDN加速服务，可以利用其区域封禁功能（部分用户需申请开通），轻松设置禁止访问的区域。
If your website uses Alibaba Cloud CDN acceleration service, you can use its region blocking feature (some users need to apply for activation) to easily set prohibited access areas.
方法二：通过宝塔面板实现禁止
Method 2: Blocking via Baota Panel
推荐使用宝塔面板（免费版/专业版均可）安装免费的Nginx防火墙，该防火墙提供【禁国外】选项，勾选即可禁止国外IP访问。
We recommend using Baota Panel (both free and professional versions) to install the free Nginx firewall, which provides a [Block Foreign] option that can be checked to prohibit foreign IP access.
方法三：使用WordPress插件禁止
Method 3: Using WordPress Plugins to Block

SEO影响与建议
SEO Impact and Recommendations
重要提示：虽然禁止国外IP可以减少部分攻击，但可能导致误杀（国内用户无法访问），对SEO优化影响较大。建议优先做好网站备份和防火墙配置，这对普通企业网站维护已足够。
Important Note: Although blocking foreign IPs can reduce some attacks, it may cause false positives (domestic users cannot access), which has a significant impact on SEO optimization. We recommend prioritizing website backups and firewall configuration, which is sufficient for general business website maintenance.
外贸网站用户注意：如果您的网站主要面向国外用户，同样可以使用上述方法禁止国内IP访问。
Note for Foreign Trade Website Users: If your website mainly targets foreign users, you can also use the above methods to block domestic IP access.
