Adding a proxy server

To add a proxy server, click either Proxy Settings in the Options menu or the corresponding item on the toolbar:

 

It will open a dialog window where you can add, edit or delete a proxy server used by Proxifier. If several proxy servers are specified, you can change their order in the chain.

WARNING: If you were using proxies before you installed the Proxifier, then you should disable any old proxy settings. This means that your applications should be configured to connect "directly" to the Internet (rather than through proxies).

 

To add a proxy server, click the Add button. It will open the form where you can specify the parameter of the proxy server:

 

IP Address
The IP address of the proxy server.

 

Port
The port number to connect to the proxy server (usually 1080, 80, 8080, 3128, etc.)

 

Protocol
The protocol used by the proxy server. Proxifier supports three types of protocols:

• SOCKS version 4 – a widely used proxy server protocol that does not support authentication. You can specify only User ID.
  Technical documentation: http://archive.socks.permeo.com/protocol/socks4.protocol
• SOCKS version 5 – has a lot more features than version 4 and supports authentication. You can specify a username and password.
  Technical documentation: http://www.ietf.org/rfc/rfc1928.txt and http://www.ietf.org/rfc/rfc1929.txt
• HTTP proxy – the most commonly used type of proxy servers working with the HTTP protocol, but if the server supports the SSL tunneling technology, it can be used for tunneling of any other protocols.
  Technical documentation: http://www.ietf.org/rfc/rfc2817.txt

  HTTP proxy with SSL tunnel support is also known as:

  • HTTPS proxy
  • CONNECT proxy
  • SSL proxy

  Attention! Not every HTTP proxy server supports SSL tunneling, therefore, not every HTTP proxy server can be used.

 

Settings (depend on the type of the proxy server)
Additional proxy server parameters.

• SOCKS proxy

  Username and Password for SOCKS v5, User ID for SOCK v4.

  SOCKS 4A extension allows remote name resolving ("DNS through proxy" feature) for SOCKS v4 proxy.
  

• HTTP proxy

  "Appear as Internet Explorer 6.0" - If checked, Proxifier emulates browser's environment and appears as Internet Explorer 6.0 (some firewalls deny all request that do not come from a browser).

  "Use NTLM authentication" - NTLM is widely used authentication protocol, it uses encryption for secure transmission of passwords. Not every proxy supports this.
