EFT Server can automatically disconnect and even ban the IP addresses of users who send an excessive number of invalid commands.
To automatically disconnect users after a defined number of invalid commands
In EFT Administrator, connect to EFT Server and click the Server tab.
In the left pane, click the Site you want to configure.
In the right pane, click the Advanced tab.
Select the Disconnect user after <n> consecutive invalid commands check box, then type the number of invalid commands allowed before you disconnect the user. You can permanently ban the user's IP address from the Site by selecting the Ban IP address after excessive invalid commands check box. You can later remove the ban on the user by removing their IP address from the list in the Site's IP Access tab.
Click Apply to save the changes on EFT Server.
