Redirect browser to different host and port

Background, Running windows 7, FF3.5, and am an admin. I recieve emails from an internal company service that has links. The problem is the links don't work from my office. If the resource is http://sub1.sub2.domain.com/page.html, I need to go to h t t p://so.me.ip:8080/page.html. (spaces in http because i am only allowed one link...)
