No, if you want a wiki entry that redirects to an external page (maybe so it shows in the area list), you would need to make an add-on that changes the URL of certain wiki pages that you define. You would not want random users creating redirects to other web sites, because it would be a great technique for SPAM and phishing.
The only similar feature I can imagine was vBulletin letting admins create forums that redirect to a different URL. I don't know if this worked in VaultWiki 3, since the "Forum Link" feature was mostly used for something else in the wiki.
Why do you need something like this? How would you use it?
