User Interface

The main window of Proxifier v4 is illustrated below.

The four main parts are Connections, Traffic, Statistics, and Output. The first three are panes, so you can adjust their layout, drag-and-drop, dock, hide, close, etc.
To enable/disable the panes, use the View -> Windows menu. The layout is saved when Proxifier restarts.
You can reset the entire layout using the View -> Reset Layout command.

Connections

This window provides a list of connections handled by Proxifier. The information about each connection is divided into the following groups (columns):

• Application: program name, process ID (if verbose output is enabled)
• Target: target host address (DNS name and/or IPv4/IPv6) and port number
• Time/Status: time elapsed since the last status change. Available statuses are Connecting (blue), Closed (gray), Failed (red), and Canceled (red). No status is displayed for an active connection.
• Rule: Proxy: rule name and proxy address with the protocol or chain name. Direct is displayed for a direct connection.

You can sort the list by any of these parameters by clicking the corresponding column header.

On the left side of the window, there is a toolbar with four buttons that can be used to

• close a connection
• terminate a process
• enable verbose output
• change the size of the list elements

The same options are available in the context menu (right click on a connection).

Traffic

The Traffic pane displays a graphic representation of the amount of information being transferred.

Blue represents incoming traffic and green outgoing traffic. The horizontal black lines indicate the data transfer rate. The white line indicates the average transfer rate for the displayed time period.

With the corresponding toolbar buttons or the context menu (right click), you can change the update rate, specify the type of graph, and clear it.

Statistics

This pane shows various statistics on Proxifier’s work, including:

• the number of connections processed by the program (active, failed, total)
• the quantity of sent and received bytes
• Proxifier’s working time since start-up

Using the corresponding toolbar buttons or the context menu (right click), you can copy the statistics to the clipboard or reset all the counters.

Output

Proxifier outputs (logs) messages to this window in real time. Each entry may contain the following information:

• date/time in the following format: MM.DD HH:MM:SS
• application name and process ID
• target (hostname and/or IPv4/IPv6 address)
• event description (e.g., connection opened/closed, resolve, error, etc.)
• additional information, such as connection statistics or an error code

You can change the extent of the output at the Log -> Screen Log menu.
Four levels are available:

• Error Only: errors and program-critical messages only
• Normal: errors and connection-related messages (open/close); recommended in the majority of cases
• Verbose: outputs all messages, including rule processing, DNS requests, and others
• Debug: outputs all messages and debug messages; generates an extensive number of messages and can be useful in troubleshooting

It is possible to write the output into a log file using the Log -> File Log menu.

Miscellaneous

Proxifier can be hidden in the System Tray when the main window is closed (View -> Icon in the System Tray).

At the bottom of the main window there is a special information area called the Status Bar that displays the DNS status, transfer rates, and number of active connections.
