You wish to change the default management ports (HTTP 8014 or HTTPS 443) used on the Symantec Endpoint Protection Manager for communication with clients.
Changing the default client management ports for Symantec Endpoint Protection 12.1 requires the following steps.
1. Create a Management Server List with the new and old port information
Clients will need a combined list of old and new ports in preparation for the change. If the clients have only the old port, they will lose communications when the port is changed on the Manager. If clients are sent only the new port, they will lose communication because they will try to use a port that has not been changed yet on the Manager.
In the Symantec Endpoint Protection Manager console, edit/create the Management Server List, and add the same Manager address twice--once with the old port, the other instance with the new port. Be sure to use any alternate names or IP addresses that may be required by name resolution on your network.
You can optionally add additional HTTP ports that Apache will listen to by inserting additional "Listen" statements in the httpd.conf file. For example, if you want to manage Endpoint Protection clients on HTTP ports 8014 and 8888 open \Program Files\Symantec Endpoint Protection Manager\apache\conf\httpd.conf and insert "Listen 8888" just below the "Listen 8014". Afterwards, you must restart the Symantec Endpoint Protection Manager service and the SEPM Webserver service. NOTE: You may add additional ports with this method, but do not change the existing default port by editing httpd.conf; use the configuration wizard so that default values are changed in the Management Server Lists.
After these changes, the Manager will stop responding to clients on the old port but the clients will be able to switch to the new port by using the Management Server List that was prepared in the preceding steps.
