Discovering NAT gateways
There are several agents that download Network Address Translation (NAT) information from known NAT gateways.
None of the agents listed in the table below is enabled in the default configuration. These agents require advanced configuration, and it is preferable not to enable them by default.
| Agent name | Function |
|---|---|
| CiscoNATTelnet | The CiscoNATTelnet agent interrogates Cisco routers
acting as NAT gateways. This agent downloads the static NAT translations
by means of TELNET from the device. The translations are then used
to identify within which part of the network a particular device exists. Note: Before enabling this agent, it is necessary to configure
Telnet access and the Telnet Helper.
|
| NATNetScreen | The NATNetScreen agent interrogates NetScreen®
Firewalls acting as NAT gateways. This agent downloads the static
NAT translations by means of TELNET from the device. The translations
are then used to identify within which part of the network a particular
device exists. Note: Before enabling this agent, it is
necessary to configure Telnet access and the Telnet Helper.
|
| NATTextFileAgent | The NATTextFileAgent mimics the function of the
other NAT gateway agents by reading NAT mapping information from a
flat file. The translations are then used to identify within which
part of the network a particular device exists. Note: Before
enabling this agent, it is necessary to configure SNMP access and
the SNMP Helper.
