5.4 The Remote Console
General description
The Remote Console is the redirected screen, keyboard and mouse of the remote host
system that KVM-0850/1650 controls.
Figure 5-5. Remote Console
The Remote Console window is a Java Applet that tries to establish its own TCP connection
to the KVM-0850/1650. The protocol that is run over this connection is neither HTTP or
HTTPS, but RFB (Remote Frame Buffer Protocol). Currently, RFB tries to establish a
connection to port number 443. Your local network environment has to allow this connection
to be made, i.e. your firewall and, in case you have a private internal network, your NAT
(Network Address Translation) settings have to be configured accordingly.
If the KVM-0850/1650 is connected to your local network environment and the connection to
the Internet is via proxy server without configuring NAT, the Remote Console will not be able
to establish the according connection. The reason is that the web proxies are not capable of
relaying the RFB protocol.
