• Enable or disable 
Reverse DNS Lookup
, which is disabled by default. 
Enable this feature unless you have no DNS server configured or have 
poor network performance because of heavy network traffic. With 
Reverse 
DNS Lookup
 enabled, when a network-related event occurs, reverse DNS 
lookup logs in the event log both the IP address and the domain name for 
the networked device associated with the event. If no domain name entry 
exists for the device, only its IP address is logged with the event. Since 
domain names generally change much less frequently than IP addresses, 
enabling reverse DNS lookup can improve the ability to identify addresses 
of networked devices that are causing events to occur.
Ping utility (control console only)
Select this option, available only in the control console, to check the network 
connection by testing whether a defined IP address or domain name responds 
to the Ping network utility.
By default, the IP address of the default gateway is used. However, you can use 
the IP address or domain name of any device known to be running on the 
network.
FTP Server
Use the 
Access
 setting to enable or disable the FTP server. The server is 
enabled by default.
