Look for references to $_SERVER['REMOTE_ADDR'] in qa-page-question.php - that's how Q2A currently retrieves the remote IP address for incrementing the page views. You can replace that code as appropriate for your setup.
In Q2A 1.4.1 I will replace all references to $_SERVER['REMOTE_ADDR'] throughout the code base with calls to a single function defined in qa-base.php, so you'll have one place where you can make the change, and it will fix everything.
