Samsung Knox firewall exceptions
Last updated March 18th, 2024
Configuring firewall exceptions is a crucial step in making sure your organization securely connects to the Knox servers and accesses the supporting resources. This process includes adding certain URLs and ports to your organization’s allowlist and accurately setting up your server and client firewalls to access different Knox cloud services.
For example, Knox Asset Intelligence enables you to get files from the supporting Amazon cloud infrastructure if you’ve configured your server firewall allowlist correctly. Similarly, adding TCP ports 5228-5230 to your client firewall allowlist ensures you can access Google services using Knox Manage. Check out the Networking requirements for Knox cloud services for more information.
To get started with configuring your firewalls:
-
Ensure ports 443 and 80 are open within your local network to reach Knox server resources.
-
Add Amazon Web Services or Google Firebase to your organization’s firewall allowlist, as Knox services might use either of these services:
-
See https://ip-ranges.amazonaws.com/ip-ranges.json for more information on IP ranges that you might have to allow to correctly use Amazon Web Services.
-
See Firebase Cloud Messaging for more information on Google Firebase services.
-
If your organization doesn’t permit connections with external servers, you can request an on-premises Knox server to handle license verification within your firewall. Samsung charges a fee for this service. For more information, contact your Samsung representative or reseller directly, or contact the Samsung Knox team.
Portal exceptions
The following table lists the URLs that you must create exceptions for in your organization’s firewall in order to use Knox services web portals on your desktop:

Depending on your enterprise’s IT policies, you might have to add the following network resources to your firewall allowlist:
If your enterprise’s IT policy restricts the use of a wildcard (*) to abbreviate a domain name, you might require the fully qualified domain name (FQDN) to reach a Knox network deployment resource.
