Thank you for the detailed reply. I however find this in R80.40 release notes kind of strange:
Appliance support for User Space Firewall (USFW)
The following appliances run in USFW mode by default:
3600, 6200, 6600, 6900, 16000T, 26000, 26000T and 23900.
Note - All other Check Point appliances will boot in kernel mode by default.
Open Server / Cloud setup, VMware will boot in USFW when using 40 cores or more.
How is 3600 any different to be on this list ? I think there is something specific in the hardware and I am curious to know what it is 🙂
