To use Integrated Windows Authentication for authentication, a DSView software administrator
must first enable it. See Client session information on page 73.
Firewalls
In a typical network configuration, as shown in Figure 4.1, the DSView software client is
located outside of the firewall and the DSView server and managed appliances reside inside the
firewall. In this case, the firewall must be configured to allow two TCP/IP ports inside the
firewall.
One TCP port (default=443) is used for the HTTPS web browser connection between the
DSView software client and the DSView server. The other TCP port (default=1078) is used for
the Avocent Proxy Protocol to tunnel video and Telnet traffic. Both ports are configurable.
If you are using the DSView management software through a firewall, we recommend the
following:
• Place the DSView server and all managed appliances within the same firewall
Demilitarized Zone (DMZ). If the managed appliances are not in the same DMZ with the
DSView server, you must configure the firewall so all data may pass between the zones
using TCP/IP ports 22 (SSH), 3211, 2068, 8192 and 3871. You must also configure the
User Datagram Protocol (UDP) port 3211 so it may pass through the firewall for initial
network discovery of appliances that do not have an IP address.
