WatchGuard Announces Fireware XTM 11.5.2 Update 1

For Original XTM 2 Series Appliance Models Only

WatchGuard has released an important update for the original XTM 2 Series appliance models (XTM 21/22/23 and the wireless models). This update corrects certain conditions that cause instability for some customers on these platforms. More specifically, this update is for appliance software only. It resolves a file system writing issue and reduces memory use during Gateway AV signature updates. If you are running one of the original XTM 2 Series appliances and are experiencing the following issues on XTM 11.5.1 or 11.5.2, we recommend applying this patch:

  • Appliance passes traffic normally but cannot be managed via WSM or Web UI
  • Appliance gradually stops passing traffic, cured by a reboot.

The update also resolves many other minor bugs. You can find more information about this update, and the issues it corrects, in the Release Notes.

Does This Release Pertain to Me?

Fireware XTM 11.5.2 Update 1 is an enhancement release designed to correct a few stability issues that may affect some original 2 Series model customers. If you manage an XTM 21, 22, or 23 appliance, and are experiencing the symptoms described above, you should download and install XTM 11.5.2 Update 1. However, if you manage a newer XTM 25 or 26 appliance, or any other XTM Series platform, you do not need this update. Please read the Release Notes before you upgrade, to understand what’s involved.

How Do I Get the Release?

XTM 2 Series owners who have a current LiveSecurity Service subscription can obtain this update without additional charge by downloading the applicable packages from the Articles & Support section of WatchGuard’s Support Center, which also includes clear installation instructions. Fireware XTM 11.5.2 Update 1 is only for the original 2 Series appliance models (XTM 21/22/23 and wireless models). As always, if you need support, please enter a support incident online or call our support staff directly.

  1. Avoid this release at all costs and ask your support guys/reseller for 11.5.2 SCP1 as this release has a seriously bad memory leak!!!!!
    After upgrading 11.4.1 on both our XTM21 and XTM510 within days i’ve had to report to our contracted support guys that the XTM510 crashed! Within seconds of reporting the issue to our support guys they said download this new release 11.5.2 SCP1 without asking too many questions about the issue. If you get this vibe then you know this has been earache to them already. If your still on 11.4.x then stay on that until a future release comes out otherwise you’ll need to downgrade like i’m going to. It’s poor that Watchguard still have this release as a download if it’s known to cause serious issues.

    From my experience though with Watchguard they are prone to crash and burn.

    Signing off,
    Very annoyed Network Admin.

    PS this release was supposed to fix:
    •Appliance passes traffic normally but cannot be managed via WSM or Web UI
    •Appliance gradually stops passing traffic, cured by a reboot

    Yeah Right!

      I’m sorry you are having issues with the firmware right now, Paul. I do want to let you know one thing though. You mention to other to use 11.5.2. CSP 1. You should know 11.5.2 Update 1 *is* CSP 1. CSP stands for Customer Specific Patch, and it is a special release of our software given out by support that fixes specific issues reported via customers. However, if we gather enough important fixes, we then combine then, test it, and then released an Update to the general customer base. So Update 1 is actually the general release of CSP 1.

      I’m not sure what your specific problems are, so support is probably better equipped to help you, but I will let you know that 11.5.3 is coming out soon, and it continues to improve some issues reported in the original 2 Series models.


  2. Good to know about it, Thanks for sharing.
