I've been working on SonicWall firewalls for about 14 years now, and I still look up the SonicWall Knowledge Base article to follow the steps for whatever it is I'm doing.
I don't work on them every day. It's not like I have a national retail network with hundreds of firewalls (did that with Meraki, and didn't touch them every day, either). Because I don't work on them every day, I wish the SonicWall configuration was a little more intuitive.
