We are obviously aware (as is everyone else!) of the rapidly-changing situation regarding the COVID-19 coronavirus. We're aware that many of you will have switched to a remote working scenario by now, and that there is no immediately obvious end date to this. We have done the same, and although remote working has always been a large part of the way Barracuda operates, due to the large scale and zero notice there have been some "teething issues" as I'm sure you have all experienced.
With that in mind, after some tweaking and testing, I am currently in the process of rolling out a patch for all BVS appliances with >2GB of RAM installed in order to attempt to increase the performance and stability of in-field appliances during these unprecedented times by freeing up more memory for use by the SSL VPN service. If your appliance has 1GB of RAM then I'm afraid there is nothing we can do - this small amount has basically zero headroom. This includes:
- physical 180/280 appliances
- some early revision physical 380 appliances
- any virtual appliances where you have NOT increased the amount of RAM available from the default 1GB that the VM image is configured with
When your appliance picks up this patch, if it is a candidate for this change, you will receive an email (to the address you used as the System Contact Address) letting you know it has been applied, and warning you that your appliance needs a reboot to make this active.
My testing looked good, early customer feedback looks good, so this will be rolled out slowly to the 220.127.116.11 and 18.104.22.168 firmware versions over the next couple of days. If this change improves things for you, that's great. If it does not, then it should never be harmful, so there is nothing lost either.
However, I need to clarify - this is still a legacy product, and nothing changes with regards to the end-of-life/end-of-support dates. This is very much a "last ditch" effort in order to try and help people through this difficult situation as we're aware that while the end date for the legacy SSL VPN is approaching, with the worldwide disruption this is not the time to want to evaluate a new appliance nor rip out your working SSL VPN solution.
