Does this work from the outside? Try connecting from a remote system. I 
have the same behaviour when trying to get to the redirected site from 
within my network, but works great when using a web browser from outside.

Have a look at the PF FAQ (from OpenBSD's website). And read the section 
about "Redirection and Reflection".

p.s. Anyone interested in purchasing an improved printed book based on the 
PF FAQ?
