ClearPass Internet Access requirements
Question: What internet access does ClearPass require for normal operation and why?
Answer: ClearPass requires access to the following URL for checking for updated plugins:
http://clearpass.arubanetworks.com (legacy
http://www.amigopod.com/webservice)This uses TCP ports 80 and 443. If an access control list will be created on a firewall to allow this traffic, please note that the IP address that clearpass.arubanetworks.com resolves to is subject to change. If you find that you are unable to get plugin updates with a valid subscription ID, then make sure this access is allowed.
For Remote Assist feature in ClearPass 6.3, ClearPass needs to be able to open a TCP 443 connection to remoteassist.arubanetworks.com.
