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.
