12 DSR Switch Installer/User Guide
In a typical configuration, as shown in Figure 2.3, the user’s computer is located outside of the
firewall, and the DSR switch resides inside the firewall.
Figure 2.3: Typical DSR Switch Firewall Configuration
To configure the firewall:
To access the DSR switch from outside a firewall, configure your firewall to forward ports 80, 443,
2068 and 8192 from its external interface to the KVM switch through the firewall’s internal
interface. Consult the manual for your firewall for specific port forwarding instructions.
NOTE: Port 8192 does not have to be forwarded for DSR1031, DSRx030 and DSRx035 switches.
2068 Transmission of KVM session data (mouse & keyboard) or transmission of video on x030 and
x035 model DSR switches
8192 Transmission of KVM session data (video) except for x030 and x035 model DSR switches
