This document describes how to use the Cisco Configuration Professional
(Cisco CP) in order to set the basic configuration of the router. Basic
configuration of the router includes configuration of the IP address, default
routing, static and dynamic routing, static and dynamic NATing, host name,
banner, secret password, user accounts, and other options. Cisco CP allows you
to configure your router in several network environments, such as small office
home office (SOHO), branch office (BO), regional office, and central site or
Enterprise headquarters, with an easy-to-use web-based management

The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.
Perform these steps in order to configure the dynamic NAT in a Cisco
Choose Configure > Router >
NAT > Basic NAT and click Launch
the selected task in order to configure basic NATing.
Choose the interface that connects to the Internet or your ISP and
choose the IP address range to which Internet access is to be shared. After
choosing this information, click Next as shown
This window appears and shows the configuration summary configured
by the user. Click Finish.
The Edit NAT Configuration window shows the configured dynamic NAT
configuration with the translated IP address overloaded (PATing). If you want
to configure the dynamic NATing with address pool, click Address
Here, information such as the pool name and IP address range with
netmask are provided. There can be times when most of the addresses in the pool
have been assigned, and the IP address pool is nearly depleted. When this
occurs, PAT can be used with a single IP address in order to satisfy additional
requests for IP addresses. Check Port Address Translation
(PAT) if you want the router to use PAT when the address pool is close
to depletion. Click OK.
Choose Address Pool in the Type field, provide the
name to the Address Pool as pool, and click
This window shows the configuration for dynamic NATing with the
address pool. Click Designate NAT Interfaces.
Use this window in order to designate the inside and outside
interfaces that you want to use in NAT translations. NAT uses the inside and
outside designations when it interprets translation rules, because translations
are performed from inside to outside, or from outside to inside.
Once designated, these interfaces are used in all NAT translation
rules. The designated interfaces appear above the Translation Rules list in the
main NAT window.
Perform these steps in order to configure static NAT in a Cisco
Choose Configure > Router >
NAT > Edit NAT Configuration and click
Add in order to configure static NATing.
Choose the Direction either from inside to outside
or from outside to inside, and specify the inside IP address to be translated
under Translate from Interface. For the Translate to
Interface area, choose the Type:
Choose IP Address if you want the
Translate from Address to be translated to an IP address
defined in the IP Address field.
Choose Interface if you want the
Translate from Address to use the address of an interface on
the router. The Translate from Address is translated to the IP
address assigned to the interface that you specify in the Interface
Check Redirect Port if you want to include port
information for the inside device in the translation. This enables you to use
the same public IP address for multiple devices, as long as the port specified
for each device is different. You must create an entry for each port mapping
for this Translated to address. Click TCP if this is a TCP
port number and click UDP if it is a UDP port number. In the
Original Port field, enter the port number on the inside device. In the
Translated Port field, enter the port number that the router is to use for this
translation. Refer to the
the Internet to Access Internal Devices section of
Network Address Translation: Getting Started.

CP automatically archives the logs in a zip file named

Once Cisco CP is launched and the community is configured, discovery of
the router takes more time than usual. Here are the Cisco CP logs that describe
the time elapsed:
July 10, 2009 8:29:19 AM EDT Discovering device test-router
July 10, 2009 8:29:20 AM EDT Last discovery clean-up elapsed time was 47 milliseconds.
July 10, 2009 8:31:13 AM EDT Discovery job allocation elapsed time was 113859 milliseconds.
July 10, 2009 8:31:13 AM EDT Authentication completed.
July 10, 2009 8:40:28 AM EDT Video feature disabled. Video feature discovery elapsed time=214375 ms

July 10, 2009 8:51:16 AM EDT Total device test-router discovery elapsed time was 1316047 milliseconds.
This issue occurs with all routers irrespective of their model and

Verify the authentication mode. If authentication does not occur
locally, then check if there is an issue with the authenticating server. Fix
any issue with the authenticating server in order to resolve this issue.
