As a general rule, using the latest browsers will produce the best results. Most proxies are supported in browsers and mobile apps today. If the only way to access the Internet from your network is through a proxy then it must be a transparent proxy or it must be configured in the browser for HTTPS connections. WebRTC does not work with proxies requiring authentication. Along with these requirements, clients may have the following rules:
- Chrome has support for proxies requiring NTLM authentication
- Firefox does not support proxies that inspect packets to validate that connections are real TLS connections, because Firefox does not support TURN over TLS
- Internet Explorer requires the installation of a plugin. Use the latest version of the IE browser when possible. IE plugin supports basic authentication. Other authentication algorithms like NTLM or Kerberos are in currently in beta.
