Manage upstream proxy
Name A meaningful name for the upstream proxy. Only alphanumeric characters, including upper case characters, commas “,”, and dots “.”, are allowed in a proxy name. The name Default is invalid because it's reserved for the name of the default proxy.
IP/Hostname The upstream proxy IP address or host name.
Port The port number to use on the upstream proxy.
Comment A comment or description.

Client credential forwarding
Option Description
Disabled Uses the Username and Password combination entered to log on to the upstream proxy.
Username only Forwards the username of the client making the request, with the Password entered when logging into the upstream proxy. This means that the upstream proxy can identify individual users without revealing their passwords. This method needs proxy authentication, NTLM authentication or NTLM identification to be turned on, otherwise usernames can't be determined by the Smoothwall Filter.
Username and password Forwards the username and password of the device making the request when logging into the upstream proxy. This could be used if both the Smoothwall Filter and the upstream proxy are authenticating against the same directory server but should be used with caution because it reveals device credentials. This method needs to use basic proxy authentication, not NTLM or any other authentication mechanism, otherwise, plain text usernames and passwords can't be determined by the Smoothwall Filter.

If you selected the Disabled option, this is the user name and password used. If you selected Username only, you only need to enter the password. If you selected Username and password, you can leave both blank.

Load balance ratio Values are relative. For example, if one upstream proxy has the value of 2 and another upstream proxy has the value of 1 and both use the round robin load balancing method, then the proxy with value of 2 will receive twice as many web requests as the proxy with value of 1.
