Redmine

Hi there

I installed redmine with success on my server, however I just have a little problem

As you can see here, I need to add :3000 to get redmine work: http://wmfs.malikania.org:3000 if you ommit it, it get a 404 error.

I'm using lighttpd, and FreeBSD but I can't see where the problem is.

Do I need to add something ? thanks for answers :)
