FINAL NOTICE: RADIUS Proxy IP Migration Required Before 10 July 2026

As part of the ongoing RADIUSaaS Proxy IP address migration, all customers using RADIUSaaS Proxies are required to complete the proxy update before 10 July 2026.

This is a mandatory change. Customers who have not completed the migration by this date will no longer be able to use the existing (legacy) RADIUS Proxy IP addresses.

Required action

Before 10 July 2026:

1. Review your network configuration and ensure your network equipment is prepared for the new RADIUS Proxy IP addresses.
2. Complete the Proxy Update from the RADIUSaaS Admin Portal.
3. Verify that your network devices are configured to communicate with the new proxy IP addresses.

Important notice

The previous proxy IP addresses will be retired after 10 July 2026. After this date, they will no longer be supported and authentication traffic using the legacy addresses may fail.

No further extensions or exceptions to this deadline will be provided. Customers who do not complete the migration before the deadline will need to update their configuration before RADIUS authentication can resume.

We recommend completing this change as soon as possible to avoid any potential service disruption.

Proxy Update

As part of the March 2026 Release, we are finalizing the migration of our managed RADIUSaaS proxies. Administrators using RADIUSaaS proxies will see a pop-up window titled “Proxy Infrastructure Update” with three options: Postpone, Go To Proxies, and Update.

If you haven’t already, ensure your network equipment is configured for the new proxy IP addresses (see How to check if you are affected for details).

When you click Update, your tenant’s proxies will be updated. Once the update completes, the legacy proxy IP addresses will no longer work.

Go To Proxies open the Proxy Settings page to review your configuration.

What You Need to Do

If your configuration uses one of the affected RADIUS proxies, you must:

1. Update your network equipment to use the new RADIUS proxy IP address.
2. Run the Proxy Update (latest by 10 July 2026).

How to check if you are affected

In general, only customers using the RADIUS protocol may be affected. If you are using RadSec only, no action is required, since you are not using the RADIUSaaS Proxy services.

Note that not every proxy server requires an IP address change.

You can verify whether your proxy configuration is impacted by logging into the RADIUSaaS Admin Web Portal:

• Navigate to your proxy configuration.
• If your proxy is affected, you will see:

  • A new IP address is listed.
  • A legacy IP address is shown in parentheses, labeled with the word "legacy".

In the following example, the proxy with the region "Europe (London)" is affected, while the proxy with the region "North America (Dallas)" is not affected. The customer is required to change the IP address for the Europe (London) proxy in their network equipment, while 165.227.229.49 is the old IP address and 139.59.200.190 is the new address:
