Hello Ben,
If you go to the help file, under the top right drop down > Help.
You will see a navigation structure on the left. Expand Laserfiche WebLink Designer > Welcome Page > Custom Links. That is where you will see information about Custom Links. Please let me know if you can not navigate to this page. Here is also the link in case you can not find it.
In regards to your issue,
You said "neither of which is functional". May I know what is not functional? Are you getting an error? Does it not respond? What behavior are you seeing?
In regards to http://test2, do you have a site that is called "test2"? As in would this be an internal site you created for your users in which they can only access when they are on a certain network connection?
Regards,
