Hi,
You were right!
The computer B (behind the router and running vnc server) also have
Kaspersky firewall.
I was stopping Kaspersky firewall but what I did not know was the Windows
default firewall was still active.
When I realize that I was surprise because when Kaspersky installed he
mentioned Windows firewall will be disabled. That happened in all other
computer that I installed Kaspersky, but not this one.
Then, I stopped Windows firewall and work right on in Active Listening mode
Than you very much to you Mike.
It work fine now.

My thought process was:
If computer B (with the router) can connect to computer A by FTP, they

Why they cannot ping each other? The router prevents that to happen.
(Spoofing protection)
It may be the router (if it has been set up to ignore pings) and, or it
may
also be the WinXP firewall which by default ignores ICMP.
The router is not stopping communication on port 20 and 21 (FTP port).
OK, so it has been configured to allow connections on these two ports.
The router is not stopping communication on port 80 (HTTP port).
Ditto.
Because Computer B can uses FTP and HTTP.
Then, I figure that I will communicate on the port number 80 to make a
test.
No, it failed
Here we come back to my previous comment: do not mix and match
ports/applications/protocols. They may interact with each other in an
adverse way.
Ok, I will try to make the server connect to the client (Default port is
5900).
No, it failed
That's because the default port for VNC Viewer launched in listening mode
is
5500, not 5900. Check this M/L and FAQs on the Real VNC website. I am
sure
it is explained somewhere how to set up the server to connect to a
listening
VNC Viewer.
I will make the server connect to the client on port 80.
No, it failed
As before. Also, port 80 is usually reserved for remote router
administration. Unless it has been set up to run an HTTP server (i.e.
forwarding port 80 to an IP address on the LAN) it will fail.
Like I said before this router (Bell / Sympatico) has a locked firmware.
If you cannot alter the port forwarding set up of the router infront of
the
VNC server then don't try to achieve a conventional VNC Viewer --> VNC
server
connection - it will definitely fail because the router will stop incoming
connections on port 5900. Then you are left with setting up the server to
accept connections from a listening VNC viewer. As I understand it you
have
to set up the current IP address of the client on the server ('accept
connections from client' setting) and open port 5500 on the client side.
If
computer A is behind a router you need to set up port forwarding and also
you
need to set up the WinXP firewall on the client to accept incoming
connections on 5500.
Come back with specific errors in response to your specific actions and we
may
get somewhere?
