I am a computer support professional,. and have discovered recently that I can 
use this great software to aid my clients remotely, so I have been installing - 
or trying to install - vnc in all kinds of different network layouts.
 
In this particular network, a client has DSL access, a tainet ca81r router, and 
Windows XP in several machines.
 
In the router, I have accessed the "virtual server" section and set the 
following port assignments:
 
External Port - Internal Port - ip address
 
5900                5900                10.0.0.6
5901                5901                10.0.0.20
 
those ips are the internals of the two computers i particularlly need to access 
in the network.
 
In both computers (10.0.0.6 and 10.0.0.20), I have done the port 5900 (in the 
10.0.0.20 i used the 5901 port) exception at the Windows firewall, and also 
unblocked the vnc viewer and server programs just in case, even though they run 
the server part.
 
To find the IP address of the network from outside, I asked my client to check 
myipaddress.com
 
The router is doing NAPT (dynamic nat) obviously configured as a router, no the 
default config for standalone dsl access with "Winpoet".
 
Now this happens: there is no way to get into the vnc servers mentioned from 
outside. After about two weeks of testing (this client resides two hours away 
from where i live) just yesterday it ocurred to me what would happen if i tried 
the other way around, that is using the "Add New Client" feature of the VNC 
Server.
 
Imagine what.... it worked perfectly.
 
I really wonder what is missing, what have I done wrong, or what test can i 
make to figure out the way to connect the straight way. I would like to point 
out that before taking the easy way out of asking i have read about a hundred 
messages from this list, and in deja.com and google.
 
The gotomyvnc.com page seems to always give positive results, as a side note. 
 
Additionally, a last doubt, maybe it4s a dumb question: will the reverse 
connection (server behind router / firewall to me, directly connected) work 
seamlessly without any port redirection, unblocking...etc?)
 
 
I will appreciate some hints. Thanks in advance.
