Proxy Settings

Configure and manage proxy server settings in InterceptSuite.

Overview​

The Proxy Settings section provides comprehensive control over proxy server configuration, including network settings, logging options, and certificate management. This is where you configure the core proxy functionality of InterceptSuite.

Proxy Server Control​

Start and Stop Proxy​

Proxy Management:

  • Start/Stop Controls - Start and stop the proxy server as needed
  • Auto-start Behavior - By default, when you open the app, the proxy automatically starts
  • Immediate Control - Changes take effect immediately

Default Configuration​

Automatic Startup Settings:

  • Default IP: 127.0.0.1 (localhost)
  • Default Port: 4444 (SOCKS5 proxy)
  • Protocol: SOCKS5
  • Auto-start: ✅ Enabled by default

Network Configuration​

SOCKS5 Proxy Settings​

Configurable Options:

  • IP Address - Select from system IP dropdown menu
  • Port Number - Customize the SOCKS5 proxy port (default: 4444)
  • Save Settings - Apply changes immediately to update proxy configuration

Configuration Process:

  1. Select IP Address - Choose from available system IPs in the dropdown
  2. Set Port Number - Enter desired port for SOCKS5 proxy
  3. Save Settings - Configuration updates immediately upon saving
  4. Immediate Effect - Proxy IP and port change instantly

UDP Relay Settings​

Fixed Configuration:

  • UDP Relay Port: 4445
  • IP Address: Same as SOCKS5 proxy IP
  • Port Editing: ❌ Not configurable - UDP relay port cannot be edited
  • Automatic Binding - UDP relay automatically uses the same IP as SOCKS5 proxy

Logging Configuration​

Verbose Logging​

Enhanced Logging Option:

  • Verbose Logging Methods - Enable detailed logging for comprehensive analysis
  • Detailed Logs - Adds more detailed information to the log section
  • Troubleshooting - Helpful for debugging and analysis purposes
  • Performance Impact - May increase log file size and processing overhead

When to Enable:

  • Debugging Issues - Enable when troubleshooting connection problems
  • Detailed Analysis - Use for comprehensive traffic analysis
  • Development/Testing - Helpful during development or testing phases

Certificate Management​

Export Certificate​

Certificate Export Functionality:

  • Export Button - Click "Export Certificate" to save CA certificate
  • DER Format - Exports InterceptSuite CA certificate in DER format
  • Private Key Export - Also exports the certificate's private key
  • File Selection - Choose export location and filename

Export Uses:

  • System Installation - Install CA certificate on client systems
  • Trust Store Management - Add to system trust stores
  • Backup Purposes - Keep backup of current certificate

Regenerate Certificate​

Certificate Regeneration:

  • Regenerate Button - Click "Regenerate Certificate" for immediate regeneration
  • Automatic Process - Deletes current CA certificate and generates new one immediately
  • Instant Replacement - New certificate is available immediately after regeneration
  • No Downtime - Process completes without stopping proxy service

When to Regenerate:

  • Security Concerns - If certificate may be compromised
  • Fresh Start - When starting new analysis projects
  • Client Issues - If clients have certificate trust issues
  • Regular Rotation - As part of security best practices

Configuration Workflow​

Initial Setup​

  1. Check Default Settings - Verify default IP (127.0.0.1) and port (4444)
  2. Customize if Needed - Select different IP or port if required
  3. Enable Verbose Logging - Turn on if detailed logs are needed
  4. Export Certificate - Export CA certificate for client installation

Ongoing Management​

  1. Monitor Proxy Status - Ensure proxy is running when needed
  2. Adjust Settings - Modify IP/port configuration as requirements change
  3. Manage Certificates - Export or regenerate certificates as needed
  4. Review Logs - Use verbose logging for troubleshooting when necessary

Important Notes​

Network Considerations​

  • IP Selection - Choose IP that clients can access
  • Port Conflicts - Ensure selected port is not used by other services
  • Firewall Rules - Configure firewall to allow traffic on selected ports

Certificate Impact​

  • Client Trust - Certificate regeneration requires client systems to reinstall new certificate
  • Immediate Effect - Certificate changes affect all active connections
  • Backup Strategy - Keep backups of certificates for recovery purposes
