Connections limit is based on Hardware ID of player's PC. System used to generate the Hardware ID is the same as used for our files licensing
1. Server Configuration (Game Server)
You can find two types of settings to control connection limit, Global and Local.
Can be configured in \DataServer\IGCDS.ini under MachineIDConnectionLimitPerGroup setting
This say how many connections can be opened for single Hardware ID for entire ServersGroup - that means for every bunch of 20 Servers, e.g. 0-19, 20-39 and so on.
Applying the changes requires reloading the configuration by selecting from application's menu Global Connections Limit reload option, alternatively by restarting DataServer applications
Can be configured under MachineIDConnectionLimitCount in GameServer.ini of every GameServer individually.
This say how many connections of single Hardware ID can be opened to actual GameServer.
Applying the changes requires reloading the configuration by selecting from application's menu Common Option reload option, alternatively by restarting GameServer applications
3. Connect Server (Anti Flood)
Do you allow multiple connections to your server? If so then set reasonable high amount for simultaneous connections to ConnectServer for MaxConnectionsPerIP setting at \ConnectServer\IGCCS.ini
To avoid potential inconveniences to players leave the setting at minimum 3-5, even if allowing only single client connection to server only
3.1. Configuring IGC Launcher (Premium) for the Anti Flood setting
Are you using IGC launcher (Premium)? There is one extra step to follow. If your Launcher Server is running within same machine as your server then it is no need to change anything. If your Launcher Server is located in different machine, outside your server configure the external IP for LauncherProxyWhiteListIP at \ConnectServer\IGCCS.ini
