Internet Proxy Support

If an ENC Client’s path to an ENC Gateway Server is blocked by an internet proxy, then it must be configured to connect through that proxy. The ENC Gateway supports SOCKS4, SOCKS5, and HTTP proxies. Authentication can be configured by an explicit user name and password or impersonation of the logged on user. The client can also use current Internet Explorer settings to locate the proxy.

The properties to be set are located in the policy node 'common components/enc/client'.

To configure a SOCKS proxy, set the parameters as follows:

• SocksProxyAddress and SocksProxyPort to identify the proxy computer
• SocksProxyAuthType to define the type of authentication to be used (basic or secure)
• SocksProxyImpersonate, which allows the client to use the credentials of the logged on user. Of course, this means that the client cannot connect unless someone is logged on
• SocksProxyUsername and SocksProxyPassword, if you want to use explicit credentials to authenticate with the proxy
• SocksProxyDiscovery, if you want the ENC Client to automatically locate the proxy using IE settings. In this case, you would usually have SocksProxyImpersonate set

To configure a HTTP proxy, set the same parameters except that “HTTP” is substituted for “Socks” in the parameter names.

Note: Proxy configuration can also be set using the encUtilCmd utility. This is useful when the computer in question is cut off from managed policy by the firewall but obviously needs policy settings in order to connect.
