How can i make it so when 24.141.132.129 tries to make a connection attempt to 216.18.0.178 on port 80 it will redirect them to another ip:port ?? or another ip:80

Is this even possible?

This is for my own learning purposes
ive always wondered if you could.

If you use a firewall (using ipfw) you can create a forwarding rule like this one..

add fwd 123.456.789.012,80 all from 24.141.132.129 to 216.18.0.178,80

not sure if that's exactly right but I know it's something like that.

You should be able to do this using mod_rewrite with apache.

Take a look at this wepage: http://www.engelschall.com/pw/apache/rewriteguide/

It's chock full of examples on how to use mod_rewite to do different things.

If you're using linux, and have ipvsadm compiled in, I prefer to use that for "port forwarding".

Another method is using natd.
Most unix boxes have an natd server.

Have a great day :)
