Once this change has been saved the Webcachewill no longer respond to default HTTP requests on this port and will beinvisible to most browsers.To access the Web interface of the Webcache in this mode type thefollowing into your browser:http://xxx.xxx.xxx.xxx:8081/where xxx.xxx.xxx.xxx is the IP address or your Webcache. You will thenbe able to administer the Webcache as before.Disabling port 80 does not change the caching operation of theWebcache. Only access to the Web interface is affected.Restricting AddressAccessBy default, the Web interface, CLI and SNMP interface of the Webcacheare available from any IP address on your network.
