Redirect domain to specific port

[Ashley M. Kirchner]

    Is there a way to redirect a hostname/domain pair to a specific 
port?  Let me explain: we have several Windows machines on our local 
network that run VNC server that folks then access from outside our 
network.  Right now everyone connects by punching in the firewall 
address with the port number for their machine, for example 
firewall.domain.com:5901 resolves to my internal machine.  The problem 
is, for me to maintain these machines it becomes a hassle trying to 
figure out whether such-n-such machine is port 5904 or 5908.  So, if I 
configure our DNS to have ashley.domain.com resolve to the firewall IP, 
is there a way I can also have it go directly to whatever port I need it 
to go to, so that all I'd have to do is enter that in my VNC connect 
box, and not worry about what port number my machine is actually on?  
Even if it means I'm maintaining an internal lookup map of what hostname 
belongs to which port, that's fine.  I'd rather not have to remember 
that every time.
