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 interface.
The information in this document is based on these software and hardware versions:
Cisco 2811 Router with Cisco IOS® Software Release 12.4(9)
Cisco CP Version 2.5
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 router:
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 here:
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 Pool.
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 OK.
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 router:
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 field.
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 Allowing the Internet to Access Internal Devices section of Configuring Network Address Translation: Getting Started.
This window shows the static NATing configuration with port redirection enabled:
Perform these steps in order to configure the other basic settings in a Cisco router:
Choose Configure > Router > Router Options and click Edit if you want to change the Hostname, Domain Name, Banner, and Enable Secret Password properties for a router.
Choose Configure > Router Access > User Accounts/View in order to add/edit/delete the User Accounts to the router.
Choose Configure > Utilities > Save Running Config to PC in order to save the configuration to the NVRAM of the router as well as the PC and to reset the current configuration to default (factory) settings.
Note: In order to use CCP to restore the configuration file stored on a computer to a router or to backup the configuration file from a router to a computer, access the Configuration Editor, and click I agree. In the Configure window, choose Import configuration from PC, and then click the replace running configuration button.

This error might be the result of a browser compatibility issue. Internet Explorer 8 changes many fundamental aspects of developing applications for IE. Cisco recommends that you downgrade Internet Explorer to version 7. You should also uninstall and reinstall Cisco CP.
Click Start > Programs > Cisco Systems > Cisco Configuration Professional > Collect Data for Tech Support. Cisco CP automatically archives the logs in a zip file named _ccptech.zip. Perform a local file system search for this file if it is not saved to your Desktop. You can send these technical logs to Cisco TAC for further troubleshooting.
Note: Close all instances of Cisco CP to get rid of any other issues in archiving the logs.
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 8:51:15 AM EDT Security feature ready - elapsed time was 860734 milliseconds.
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 platform. In addition, there are no memory or CPU related issues on the routers.
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.
