Can Homepage Redirect Also Apply to All URLs?

Hi, i have a newbie question.
I recently started redirecting my homepage (mysite.com) to another website.
However, all posts from (mysite.com) dont redirect.

Do i HAVE to create a redirect for every single post on (mysite.com)? That would be a lot of work.

Thanks!
