Remote Management Hosts
The Remote Management Host section of the Security Administration page enables you to set up the legal IP
addresses from which authorized persons can configure the Model 2160. This is the most secure way for the
network administrator to set up the legal address of configuration.
Figure 48. Remote Management Host section
A configuration of 0.0.0.0 will allow all hosts on Internet or LAN to access the Model 2160. If you leave the
trusted host list completely blank, you will block all PCs on the WAN from accessing the Model 2160. On the
other hand, only PCs in the LAN can access the Model 2160. If you type the exact IP address in the filed, only
that host can access the Model 2160.

figure other options.
SNMP Administration
Simple Network Management Protocol (SNMP) provides for the exchange of messages between a network
management client and a network management agent for remote management of network nodes. These mes-
sages contain requests to get and set variables that exist in network nodes in order to obtain statistics, set con-
figuration parameters, and monitor network events. SNMP communications can occur over the LAN or WAN
connection.
The Model 2160 can generate SNMP traps to indicate alarm conditions, and it relies on SNMP community
strings to implement SNMP security. This Model 2160 support both MIB I and MIB II.
