To follow up on what Lee is saying and what you asked ...
The software that is used to set up your router will most likely have
an advanced option (I wish I could be more specific, but each router
manufacturer handles this slightly differently, some use web-browser
based set-ups and some use stand-alone programs, etc.) that allows you
to designate how it handles types of request that come in --- just as
Lee has outlined. You can, in one way or another, tell it to send those
requests to specific machines via their address and then that kind of
traffic flows only to that machine and the rest of the traffic is
handled in the normal way.

p.s. You can then talk to your home machine from work and vice versa
using the way that Lee has earlier described, but you will need to use
the IP address that the router uses to connect to the internet, it will
have the 205.xxx.xxx.xxx form.
