Our company likes to utilize PROTECTLI devices for firewall solutions for clients. We have encountered issues as of late with the newest pfSense 2.4.4.
We noticed some impacting issues with routine maintenance and I wanted to share this information with you to help prevent downtime. We were creating a memstick bootable USB with something like Rufus when our ZALMAN device install method wouldn't work.
This would cause us to go into the BIOS of the PROTECTLI and change all of the CSM settings to DISABLED. This would allow the boot process to proceed, but the information in the link may be a more reasonable option if we were to leave CSM enabled. Please refer to the link below on the steps on how to prevent these issues or overcome installing issues.
If your pfSense is not somewhat up to date, you may have issues with the updater also installing newer versions. One option to adjust and check is below. Long story short, adjusting the maximum table entries allows for more lines of code to be entered which is necessary for some newer versions.
Increase the Firewall Maximum Table Entries size to 400000 in System > Advanced, Firewall & NAT
I hope you found the above information helpful.
