KEMP WAF - What steps to take if the LoadMaster cannot contact ALSI to download daily reputation data

Issue: The LoadMaster is unable to download the daily reputation data for WAF and GLSB and is reporting that the ASLI server is unreachable. A packet capture, taken on the LoadMaster can confirm if you are able to reach the ALSI server. The FQDN will differ depending on the LoadMaster firmware in use.

  • LoadMaster firmware version 7.2.53 or above (or Long Term Support (LTS) and above):

  • LoadMaster firmware versions below 7.2.53 (or below LTS): and

 This is usually the case when there is a local search domain is configured on the LoadMaster.

The search domain is configured under System Configuration > Network Setup > Host & DNS Configuration.

Check if the specific domain name for your firmware can be resolved by going to System Configuration > Logging Options > System Log Files > Debug Options > Ping Host, and change the Interface to Automatic.

If it fails, remove the search domain or confirm the DNS server can resolve appropriate domain name, then re-try the download.
