Figure 5-21 Device Security
Force HTTPS
If this option is enabled access to the web front-end is only possible using an HTTPS
connection. The IP-KVM will not listen on the HTTP port for incoming connections.
In case you want to create your own SSL certificate that is used to identify the IP-KVM
refer to the Section called Certificate.
KVM encryption
This option controls the encryption of the RFB protocol. RFB is used by the Remote
Console to transmit both the screen data to the administrator machine and keyboard and
mouse data back to the host. If set to “Off” no encryption will be used. If set to ”Try” the
applet tries to make an encrypted connection. In case connection establishment fails for
any reason an unencrypted connection will be used.
If set to “Force” the applet tries to make an encrypted connection with certificate. An error
will be reported in case connection establishment fails.
Group-based System Access Control
This is the IP filtering function, it keeps unauthorized hosts from accessing to the
IP-KVM by specifying IP filtering rules. It is important to fully understand what an IP
filter is. If you don't fully understand this, you will get unexpected results against your
original plan.
