Most routers will support port forwarding (also called pinholes). Your 
manual should tell you how to open the particular ports you need and 
forward them to particular machines on the LAN.

If you are working with Windows, hovering the cursor over the VNC icon will 
report the internal IP address - such as 192.168.0.1, .2, etc. You just 
forward the ports on the router to the particular machine based on it's 
internal address.

For example, I have a Cayman router. It lets me forward ports as follows;

Machine Start port      End 
port        Protocol        IP              Internal port

Machine 
1       5800            5800            tcp/ip          192.168.0.1 
192.168.0.1
Machine 
1a      5900            5900            tcp/ip          192.168.0.1 
192.168.0.1
Machine 
2       5801            5801            tcp/ip          192.168.0.2 
192.168.0.2
Machine 
2a      5901            5901            tcp/ip          192.168.0.2 
192.168.0.2

(There are only two machines listed above - don't know why Cayman makes you 
do it this way instead of one listing with start and end ports on the same 
line, but they do. Machine 1 and Machine 1a are the same machine - another 
oddity of the way Cayman has it set up. My Netgear router is slightly 
different, but you get the idea. I think I remember Linksys being somewhat 
more obvious, but I don't have one handy to check just now.

On each machine, you then go to the VNC icon (assuming you are running it 
as a service), select properties,  and un-check the auto selection and 
instead specify the particular port that it will be listening on. For 
example, Machine 2's VNC will be set to listen on 2.

Seems a little peculiar, but it works fine.

HTH!
