Web Proxy Auto-Discovery Protocol

The Web Proxy Auto-Discovery Protocol (WPAD) allows RealPresence ITP systems to route network traffic outside enterprise networks.

When your RealPresence ITP system uses Web Proxy, inbound HTTP and HTTPS traffic (ports 80 and 443) is directed to the configured proxy or proxies.

The Proxy auto-config (PAC) file is a configuration file executed by the system to determine the proxy for a specified URL.

Your system can authenticate with a proxy using the following methods:

  • Digest authentication (with either MD-5 or SHA-256 digest)
  • NTLM authentication (only NTLMv2 is supported)
  • Basic authentication (this insecure method is disabled by default)
  • No authentication (or null authentication, meaning the proxy server doesn’t require credentials)

By default, the Basic authentication is disabled. You can enable Basic authentication in RealPresence ITP system web interface.

Your system supports the following services when configured to use a web proxy:

  • Directory servers
  • Provisioning service
  • Calendaring service
  • Recording service
  • Software updates
  • Uploading logs
