But some clients can't recognize this format (see this [issue](https://github.com/MatsuriDayo/nekoray/issues/104)), so Reqable provides an option to switch the format.

+### Record Mode
+
+:::caution Attention
+
+If you are not familiar with this function, please keep the **VPN** mode.
+
+:::
+
+On the Android side of Reqable, we provide two`record modes`to capture network traffic:  **Proxy Mode** and **VPN Mode**。
+

+
+- **Proxy Mode**
+ Configure the IP and port of Reqable's MITM server into the system's network proxy settings. If the application supports it, it will read the system's network proxy settings for network requests, allowing Reqable to capture the traffic. On the PC side, Reqable only supports this mode and can automatically configure the system proxy settings with one click. On the mobile side, you need to manually configure the system proxy, and if the application does not support proxy settings, it may not be able to capture the traffic.
+
+- **VPN Mode**
+ Also known as TUN mode, it forces the application's network traffic into the VPN virtual network card, which is undetectable by the application itself. The virtual network card automatically forwards the traffic to Reqable's MITM server for traffic analysis. Mechanically speaking, the VPN mode can automatically intercept traffic, similar to a transparent proxy, with the application itself being unaware, offering stronger operability. Currently, only the mobile side of Reqable supports VPN mode.

+
+:::
+
+在Reqable的Android端，我们提供了两种`记录模式`来捕获网络流量: **代理模式** 和 **VPN模式**。
+
+![](arts/proxy_05.png)
+
+- **代理模式**
+ 将 Reqable 的 MITM 服务器的 IP 和端口配置到系统的网络代理配置中，若应用程序支持，将会读取系统网络代理配置进行网络请求，这样 Reqable 就能捕获到流量了。在 PC 端，Reqable 只支持这种模式，且能一键自动配置系统代理设置。在移动端中需要手动配置系统代理，如果应用程序不支持代理设置，可能无法捕获到流量。
+
+- **VPN模式**
+ 又称 TUN 模式，将强制应用网络流量进入 VPN 虚拟网卡，应用本身是无感知的。虚拟网卡将流量自动转发到 Reqable 的 MITM 服务器，进行流量分析。从机制上来讲， VPN 模式可以自动化拦截流量，类似透明代理，应用本身无感知，可操作性更强。目前，Reqable 只有手机端支持 VPN 模式。
