New to VNC Need some help

You probably have to do three things.

First, as you alluded to, you (the VNC viewer) need to know those dynamic IP

Second, you have to determine whether those DSL Routers are doing NAT; they
probably are (the clue: they all use a gateway address of

In that case you have to set up port forwarding on your DSL routers, with
each VNC port forwarding to a different computer on the network.  Ie,
forward port 5901 to computer A, 5902 to computer B, etc.
When you connect from VNC viewer you would specify :1 to connect to computer
A and :2 to connect to computer B.  Of course the colon must be preceded by
the real, dynamic IP address.

FYI, this procedure is not unique to VNC.  This would be the case if you
wanted to Telnet into those boxes, or FTP, or access them as web servers, or
almost anything else.
