I am experiencing problems using a personal firewall on your site?

You may experience problems when using the reservation application.  If so, this might be caused by an Internet security software package installed on your computer (such as Norton, McAfee or ZoneAlarm). Please add the domains pib.stenaline.com and secure.stenaline.com to the list of secure domains in your software to reduce these problem. 

In Internet Explorer, follow these steps:

Tools > Internet Options Security tab > Trusted sites > Click the "Sites" button. 

Add http://secure.stenaline.com to trusted sites. 

Please note that the "Require server verification (https:).." box must not be checked.
