circumstances.
Destination
Port Enter the port number of the device on the WAN side of the network that will be accessing
the Virtual Server currently being configured. Commonly, this port number is identical to the
Private Port number. Existing Virtual Servers listed already have their well-known port
number listed yet this may need to be changed in certain circumstances. You can specify a
range of ports, a single port, save ports, or any port.
Click the Apply button to put the new virtual server configuration set or modification into effect. Any
server sets configured in the menu will appear in the Virtual Server List with the new settings. The ADSL2+
Router must save the new settings and reboot before the new virtual server configurations are applied.
To remove any configuration set from the Virtual Server List, click on the trashcan icon for set you want
to delete.
5.3 SNMP Configuration
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically
for managing and monitoring network devices. SNMP enables network management stations to read and
modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure
system features for proper operation, monitor performance and detect potential problems in the Switch,
switch group or network.
The default community strings for the Switch used for SNMP v.1 and v.2 management access are:
public - Allows authorized management stations to retrieve MIB objects.
private - Allows authorized management stations to retrieve and modify MIB objects.

Traps are messages that alert network personnel of events that occur on the Switch. The events can be as
serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change.
The Switch generates traps and sends them to the trap recipient (or network manager). Typical traps include
trap messages for Authentication Failure, Topology Change and Broadcast\Multicast Storm.
