Redirects and IP addresses

Does anyone know:

If I redirect from one site on my box to another site, will it change
the headers to show that the IP address is the one for my box, or will
it remain the IP of the person that’s being redirected?

I’m assuming the latter because I think that the redirect touches their
browser before going on to where it’s redirected to, but I don’t know
enough about back-end stuff :slight_smile:

Thanks in advance.
