SFTP Proxy Server Settings

If your computer uses a proxy server to access the internet, use this dialog to enter the settings for the proxy server for use by the WinZip® SFTP cloud service. Your system administrator should be able to provide values for these settings. The dialog has the following options:

  • Use Internet Explorer defaults: Check this checkbox to use the same proxy server settings that Internet Explorer uses to access the internet. Uncheck this checkbox to enable he next five fields and manually specify the proxy settings for WinZip® to use.
  • Proxy type: Select the proxy type. The valid proxy types are Socks4, Socks5, and Http.
  • Proxy Host: Enter the proxy server host name or IP address. If there are multiple entries, enter them in a space-delimited string. The individual proxy listings can include a port number. 

    You can list a proxy for a specific protocol using a string that follow the format =://:. The valid protocols are HTTP, SOCKS4, and SOCKS5. For example, to list a SOCKS4 proxy, a valid string would be socks4=socks4://socks4_proxy_name:1000, where socks4_proxy_name is the name of the SOCKS4 proxy server and 1000 is the port number that is used to access it. If the proxy server uses the default port number for that protocol, the port number may be omitted. If a proxy name is listed by itself, it is used as the default proxy for any protocol that does not also have a specific proxy specified. For example, http=https://http_proxy all_other_proxy would use the http_proxy server for any HTTP operation and all other protocols would use the all_other_proxy server.

  • User Name and Password: enter the username and password, if required, to be used when authenticating to the proxy server(s).
