At the moment, there are only 2 ways to play on the network: GameRanger and Hamachi.
It is about them that will be discussed in this guide.
All information about these methods will be presented in the form of an algorithm of actions for each of the presented methods individually.

In both cases, for normal functioning, the game must be run as administrator !!!

Algorithm of actions:

• 1. Download GameRanger from the official website: http://www.gameranger.com/
  
• 2. Install it and register if necessary, who already has an account will just need to log in.
  
• 3. After the GameRanger is launched, go to Edit-> Options. A tab with a list of games opens, you need to select our game and specify the path to the location of Iron3d.exe (both the first and second parts can be used)
  
• 4. For server creators): Click Host, in the window that opens select the necessary options (Number of players, password for the room, etc.) and click OK. Now you just have to wait for the players and press start.
  
• 4.1 For those who join the server: select the desired room, click on it and click Join.
  
• 5. Play.

(For experienced users, GameRanger has a contact list through which you can invite players to your room)

This method is the easiest and works.

Algorithm of actions:

• 1) Download RadminVPN with https://www.radmin-vpn.com/ru/
  
• 2) Install and run as administrator.
  
• 3) Create a network or join a friend's network. Similar to actions 7-9 of Algorithm of Hamachi.
  
• 4) Play using IP addresses from RadminVpn

Algorithm of actions:

• 1. Download Hamachi from the official website: https://www.vpn.net/
  
• 2. Register on the site.
  
• 3. Install Hamachi.
  
• 4. Add Hamachi to the exceptions of the firewall and antivirus.
  
• 5. Check the priority of the Hamachi adapter in the network connection settings.
  Importantly, the adapter should be in the first place among all connections. Priority is checked in the
  control panel-> Network and Internet-> Network and Sharing Center-> change adapter settings.
  
• 6. Configure Hamachi according to the some articles in internet =).
  Some articles suggest disabling encryption, but I immediately say that this does not work for everyone. So if suddenly a yellow triangle appears with an exclamation mark on the network for other network participants, just turn encryption back on.
  
• 7. Create a ILAN network (Internal Local Area Network) into which players will connect. Set the network name and password.
  
• 8. Make sure that all players on the left have a green circle.
  If any other as yellow triangle or red circle, right-click on the nickname player in the hamachi and in the context menu that appears, select the Diagnostic item.
  Next, a diagnostic window will appear, click start in it. After that, a diagnosis will occur and hamachi will give the result in a convenient form, quite simple to understand.
  
• 9. if everything is ready and verified, then you can run the game and create / join the server.

Of the three methods presented, I recommend GameRanger and RadminVPN, because only this methods is really work for me.

That's all. If you have questions, write here - I will answer as far as possible.
