Use this policy to configure the use of additional SOCKS proxies that are required for some advanced network topologies. When enabled, the client will examine the "SOCKS protocol version" setting. If connection via SOCKS is not disabled, the client will attempt to connect using the SOCKS proxy specified by the "Proxy host names" and "Proxy ports" settings. The client supports connections using either SOCKS v4 or SOCKS v5 proxy servers. Alternatively, it can attempt to automatically detect the version being used by the proxy server. Troubleshooting: The SOCKS proxy settings are designed for traversing a proxy in addition to the primary or alternative proxy server. When traversing only a single proxy, these SOCKS proxy settings should be disabled.
