Logging in as the Server Administrator
Ignore this section if you are already logged in as an administrator.
Right-click anywhere in the white space inside the Ventrilo Client, go to Server Admin, and click Login – This will bring up the Enter Admin Password menu.
Enter your server's Admin Password and click OK.
You will now be logged in as an administrator on your server, which will be denoted by a capital “A” next to your server's name in the upper-left corner of the server.
If the password was entered incorrectly you will automatically be kicked from the server, and receive an error message informing you as such. In this situation simply reconnect to the server, repeat the process, and ensure that the password is entered without any typos.
Allowing Duplicate IPs
Right-click anywhere in the Ventrilo white space, go to Server Admin, and click User Editor.
Select the user profile from the Current Users list on the left side of the User Editor you wish to edit.
Go to the Network Tab, open the Duplicate IPs drop down menu and select the desired permission.
Click the Update button to apply the changes to your server.
Congratulations! You have successfully allowed duplicate IP Addresses for a user profile. Repeat this process for any other users that you would like to permit duplicate IPs for.
