Mobile Device Proxy Configuration

Mobile device proxy configuration allows a computer acting as a proxy server (such as one running Fiddler Classic) to intercept and inspect network traffic from a connected mobile device.^[600-developer__tools__mobile__Fiddler-Classic.md]

Setup Procedure

To successfully capture traffic, the mobile device's network settings must be adjusted to route traffic through the host machine.^[600-developer__tools__mobile__Fiddler-Classic.md]

1. Configure Host Proxy

The host machine must be configured to allow remote connections. In tools like Fiddler Classic, this involves: * Enabling the proxy to act as a gateway. * Checking the "Allow remote computers to connect" option in the proxy settings menu.^[600-developer__tools__mobile__Fiddler-Classic.md]

2. Adjust Device Network Settings

The mobile device requires manual network configuration to point to the host machine's IP address. * Proxy Host: Enter the local IP address of the computer running the proxy software. * Port: Enter the listening port configured on the host (e.g., port 8888).^[600-developer__tools__mobile__Fiddler-Classic.md]

3. HTTPS Decryption

To view the content of HTTPS traffic, the mobile device must trust the proxy server's certificate. * The mobile device's browser must visit the specific proxy server address (e.g., http://127.0.0.1:8888) to download the CA Root certificate. * The certificate must be downloaded and installed/added to the device's trusted credentials store.^[600-developer__tools__mobile__Fiddler-Classic.md]
