What's this?

GProxy DLL is a reconnection plugin for Warcraft III. It reconnects you automatically whenever you are disconnected from a game. It is based on GProxy++ by Varlock and GProxy GUI by LadyGaga, made into an Warcraft III plugin with various bugfixes and optimizations by h3rmit.

How to install

Download MyMGN GProxy DLL v.0.09

Note: GProxy DLL installs a new gateway in Warcraft III and sets it as the default gateway. To change the gateway, just click on the magnifier icon next to the Battle.net button. The default gateways are Europe, US East, US West and Asia. Below them you will see a new one, GProxy.

Battle.net servers

By default, GProxy DLL connects you to europe.battle.net. In order to connect to a different server, download and extract one of the following in your Warcraft III folder:

Since version 0.07, GProxy DLL also supports PvPGN servers:

Note: In order to connect to a PvPGN server, you need to use the appropriate loader provided by the PvPGN server. GProxy DLL does not replace the PvPGN loader.




GProxy reconnects you automatically to the game that you were disconnected from, as soon as your internet connection is restored, up to 5 minutes later.


GProxy spoofchecks you automatically when you enter a game.

Game start notification

When your game starts, GProxy restores the window of Warcraft III, if it had previously been minimized.

Ignore whispers the easy way

Tired of getting annoying whispers? GProxy makes the squelch commands in Battle.net smarter, and adds shorthand aliases so that you can easily ignore anyone bothering you.

  • /i or /ignore

    Ignores the last player who has whispered to you.
    Also works by typing /s or /squelch

  • /i partial_name

    Ignores a player who has whispered you and has a name containing the text you entered.

    E.g.: If a player with a long or hard to read name like I1lL1lll1I1I1II has whispered you, you can ignore them by just typing:
    /i L1

  • /ui or /unignore

    Unignores the last player you have ignored.You can repeat the command to unignore the previous player you have ignored, and then the one before that, etc.
    Also works by typing /us or /unsquelch

  • /ui partial_name

    Unignores a player you had previously ignored and his name contains the text you entered.

    E.g.: If you had previously ignored a player I1lL1lll1I1I1II, you can unignore them by typing:
    /ui L1

Technical stuff


The following optional configuration directives are supported in gproxy.cfg:

  • log

    Enables GProxy logging. The value specifies the filename of the logfile. If it is empty, the logging is disabled.
    Default value: (empty)

  • bnet_hostname

    Specifies the Battle.net server that GProxy connects to. Can be europe.battle.net, useast.battle.net, uswest.battle.net or asia.battle.net .
    Default value: europe.battle.net

  • bnet_game_indicator

    Prefix added to the game names that support reconnect via GProxy. The prefix is both shown in the custom game list and the Lobby.
    Default value: (empty)

  • bot_port

    The port at which GProxy listens for Warcraft III game connections. The port is used only for internal purposes (proxying) and does not need port forwarding.
    Default value: 6125

A few things about the GProxy Extended Protocol

Varlock's original GProxy worked by sending empty actions between each real in-game action (for more information, read his original post). This has the following drawbacks:

  • Increased bandwidth usage and lag for non-GProxy players.
  • The reconnection time is limited.
  • When a player disconnects, the game stops and everyone has to wait for him.

I have studied Warcraft III extensively, and I found out I can just dump the empty actions and still keep Warcraft III alive. GProxy DLL patches the timeout interval of Warcraft from 60 seconds to any desirable value requested by the GHost++ bot.

Using the new GProxy Extended protocol:

  • The reconnection feature no longer causes extra delays for any player.
  • The reconnection time is unlimited, and can be configured in GHost++.
  • When a player disconnects, all the other players can continue playing while waiting for him to reconnect, just like LoL or Dota2. Of course, they can always pause the game manually, if it is deemed necessary.
  • GProxy DLL disables the "Disconnect" button in the "Waiting for Host" window, so that players no longer leave the game accidentally while trying to reconnect. Of course, if the bot rejects the reconnection, the time limit is reached or the reconnection is impossible, the button is re-enabled.

The GProxy Extended protocol requires server-side implementation in GHost++, and it is currently used only in games hosted by MyMGN.
