Thomas:
Hello! You're unable to connect from work to home because
(most likely) your workplace firewall is blocking outgoing connections
to the TCP port that your VNC Server at home is listening to. That is,
by default, a VNC Server listens to TCP 5900. If you changed that to
TCP 443, and tried to connect from work (eg, 100.200.300.400::443),
you may have more success. Many workplace firewalls block connections
to anyting but a handful of "common" applications, like HTP, HTTP,
and HTTPS. The last one, HTTPS, uses TCP 443, and it's the best one
to "borrow" when you need to.
If that doesn't work, you may have to "tunnel" the connection.
Here is an example of using EchoVNC to tunnel a RealVNC connection from
home to work (which is usually harder):
1. Download EchoVNC 2.31 and install it on the PC you want to
take remote control of (eg, your work PC). The startup Wizard
will automatically detect your RealVNC server and configure
itself to work with it correctly.
2. During the Startup Wizard process, login to the demo echoServer
at "demo.echovnc.com", password "demo2007". If your workplace
firewall doesn't allow that, try "demo.echovnc.com:443", same
password. The login name you use in this step is how you'll
connect to this PC in the future.
3. Download EchoVNC 2.31 and install it on the PC you want to
take remote control from (eg, your home PC). During the Startup
Wizard process, login to the same echoServer you chose in step
#2 above.
4. Start the Viewer. In the Options screen, tell EchoVNC to use
the RealVNC Viewer installed on your PC.
Once those steps are done...in the main GUI of the Viewer,
use the little "search box" to type in the login name of your VNC
Server, the one you connected with in step #2. Once you find it,
just double click. That should do it!
cheers,

Hi all,
I installed the Real VNC Server on my computer at home and the client
viewer on the computer in my office (in the company). I open the viewer
in my office trying to connect the server at home, but I got error:
"unable to connect to host: Connection timed out (10060)".
I call my friend in other city at home trying to connect to my
computer at home, it runs. I am not sure it's because of the fire wall
of my company.
Besides, if I ping the ip-address of the computer at home. I get response.
Someone knows how to overcome it?
Regards
