TLRS2 IP Address Change

On March 25th at 9pm ET we will change the IP addresses for one of the eduroam-US RADIUS servers (TLRS2.eduroam.us).

It is critical to note that if you have not already successfully updated your RADIUS and network configurations for TLRS1 your eduroam service WILL fail when the cutover for TLRS2 occurs on March 25th. Please take a moment to check your institution’s status on the IP Change Status Page. If your institution appears as failing please review the troubleshooting steps on this page.

Please take immediate action to prevent a loss of service when we make the required configuration changes on Monday March 25th at 9 p.m. ET. Failure to make these changes could cause a loss of eduroam service for your organization.

If you are using explicit IP addresses

  • You must add a new client for the new TLRS2 IP address before the change.
  • You must change your proxy IP address to the new TLRS2 IP address before the change.
  • You must check your firewall rules to allow traffic from the new IP address before the change.
  • After the change you can remove all references to the old IP address.

If you are using DNS for your configuration

  • You must restart your service at 9 PM so that it will pickup the new IP address.
  • You must also check your firewall rules to allow traffic from the new IP address.

Testing Your Configuration
(Note: checking your campus RADIUS logs might not be sufficient.)

Steps to check that your peering is working, using logs.

Go to https://www.eduroam.us/admin-login and sign in. Navigate to the Log Viewer Tool (Administration Menu)
The peering identifier is normally your primary realm and should be easy to find in the displayed logs.

For Service Providers

  • Under Search Options: Filter by Client Identifier = <peering identifier>.
  • If you see recent accepted OR rejected requests then your peering is working as an SP.

For Identity Providers

  • Under Search Options: Filter by Username = <peering identifier>.
  • If you see recent accepted requests then your peering is working as an IdP.

Steps to actively test that your peering is working, using testing tools.

For Service Providers

  • Using the Test Account Tool (Administration Menu), create a test account and use it on a device and try to connect to your local 'eduroam' SSID.

For Identity Providers

  • Using the Realm Testing Tool (Administration Menu) you can simulate one of your users roaming to another institution (Cliewnt Identifier = 'Web Site' in the Log Viewer).
