If you want make a link in you mod control panel only need make this.
Open modcp/index.php
Search:
Code:
if (can_moderate(0, 'canbanusers'))
{
$canuser = true;
construct_nav_option($vbphrase['ban_user'], 'banning.php?do=banuser', '<br />');
Add:
Code:
construct_nav_option('Ban IP/Mail', 'ipban.php', '<br />');
Or create a new vbphrase and replace with this
Code:
construct_nav_option($vbphrase['banIP'], 'ipban.php', '<br />');
