Firewall exceptions
Last updated August 18th, 2023
This topic describes the firewall exceptions enterprises must utilize to extend beyond their own local and protected network domains and securely reach and connect to the Knox Mobile Enrollment server and its supporting Knox server resources. This topic contains the URLs and port numbers that require allowance of a trusted site for enterprises attempting to reach destination Knox servers.
These server resources can include the following Knox services:
-
Samsung license Servers — When you activate Knox services, devices need to verify their license keys. Devices periodically check their licenses a few times a week.
-
Samsung SDS IAM & EMM — If utilizing an EMM, devices will need to access Web based EMM consoles and storage sites.
-
Samsung ActiveSync Server — If using Exchange ActiveSync, you will require an ActiveSync Server connection so the Email client can successfully reach the ActiveSync Server.
Note
If your enterprise is highly regulated, and does not permit a connection with an external server, you can request an on-premise Knox Server, which handles license verification within your firewall. Samsung charges an extra fee for this service. For more information, contact your Samsung representative or reseller.
Ports 443 and 80 must be open within your local network domain to reach Knox server resources.
Note
Knox Cloud Services can utilize both Amazon Web Services (AWS) and Google Firebase. Both services may also warrant an allowlist within your organization’s firewall policy.
For information on the AWS that may require allowlist inclusion, go to: https://ip-ranges.amazonaws.com/ip-ranges.json.
For information on the Google Firebase services that may require allowlist inclusion, go to: https://firebase.google.com/docs/cloud-messaging/concept-options#ports_and_your_firewall.
