# proxy\_bind

<mark style="color:blue;">**proxy\_bind**</mark>指令<mark style="color:blue;">**强制将与代理主机的连接绑定到指定的IP地址**</mark>。通俗来讲就是，**在配置了多个基于名称或者基于IP的主机的情况下，如果我们希望代理连接由指定的主机处理，就可以使用该指令进行配置**，其语法结构为：

```nginx
proxy_bind address;
```

其中，<mark style="color:blue;">**address**</mark>为指定主机的IP地址。

{% hint style="info" %}
If your proxy server has several network interfaces, sometimes you might need to choose a particular source IP address for connecting to a proxied server or an upstream. This may be useful if a proxied server behind NGINX is configured to accept connections from particular IP networks or IP address ranges.
