Introduction
This document describes how to integrate a NAC Guest Server (NGS) with Wireless LAN Controllers
(WLCs) and an Adaptive Security Appliance (ASA) to provide URL logging and reporting of guest traffic.
Many companies have a requirement to monitor guest traffic, and this paper provides information on how to
configure the Cisco components to meet that requirement.
Note that there are multiple Cisco solutions to configure Guest Access in a Cisco Network. This article
focuses on the method that uses the WLC as the enabling technology. The WLC has the unique ability to
tunnel traffic from the network edge to the Internet with EoIP. This feature eliminates the need to deploy
VPNs or ACLs within the network infrastructure to restrict guest traffic from leaking into the internal network
of the company.
The bulk of this article covers Integrated URL Logging and Reporting in a wireless−guest network, but
this feature can be configured in a wired−guest network, as well. Appendix A provides details for a
wired−guest network.
