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 DSR 1031, DSRx030 and DSRx035 switches.
To connect to the DSR switch on-board web interface:
Open a web browser and enter the external IP address of the firewall. The DSR Explorer will
open and prompt you to login.
