java.net No route to Host Exception

[zeahr zeahr]

hello,

I'm new to RealVNC, I setup a server in My home's PC.
I'd like to connect from my Company's PC but I have a problem.
Here is the situation:
The VNC server is behind a router/firewall.
RealVNC PC server IP: 192.168.0.2
VNC Listening Port: 5900
Java HTTP port      : 8080
------
Router Setting:
Port 5900 mapped to 192.168.0.2
Port 8080 mapped to 192.168.0.2
------
In my company's PC, we used the port 8080 with Username and Password
to connect to the internet.
I tried to connect to my server using IE6 with Java enabled and it
loaded successfully.
http://mydomain.com:8080
A Java applet appears then I input at the server window: mydomain.com:0
and I received this message "java.net No route to Host Exception...."
What is the problem with my connection?
Thanks
