Certs absolutely can have something to do with UTM firewalls that are doing scanning at the network layer. If you're hosting your own website, then you could install your cert on the firewall, it would open the packets, scan them, then seal them back up and send them to your server.
The that is nothing to do with a firewall and everything to do with a MITM webserver intercepting the traffic. Perfectly valid reasons to do so if desired. But it has nothing to do with a firewall.
But the firewall is what is inspecting the traffic, maybe I'm misunderstanding you.

That is MITM interception of web traffic and has nothing to do with a firewall. Obviously, you can run said service on the same piece of hardware as your firewall, but it is still not a damned firewall.

Are you talking about certificate warnings when accessing the router? Or are you talking about certificate warnings when the firewall is a man-in-the-middle?
The link is referencing the latter.

Okay, just trying to understand what you're trying to saying because I thought the firewall was intercepting and inspecting the traffic. Not another service.

No, it is a webserver.

I have these moments all the time here. Jared is correct. I'm confused frequently here

Found an okay link here explaining it a bit...

In your case it is.. because you are using a UTM -
JB, now who's pulling a Scott?
His UTM is a firewall and a content filter.

Yeah, don't be like that guy.

It IS important to realize that UTMs are just like MS SBS server... lots of different things jammed into a single box breaking standard best practices around separation of duties. The routing/firewall and other functions come from different components of the UTM. It is all one UTM on one hand, but it is a collection of random services on the other. If you were building your own UTM, you'd not use the "it's all one thing" terminology. It is only when thinking of it as a black box that it seems like are all one thing.

That much I do understand... I was just under the misconception that the inspection was happening on the firewall side of services, rather than proxy/web server side of services. I had overlooked that in the link I posted as a response.
But I guess one could simply state that a firewall does nothing more than allow traffic to pass/redirect/drop/or be blocked based on rules, nothing more. It's not until you add additional services that you can inspect traffic, filter web content, or setup a secure tunnel/VPN.

Why? There is nothing wrong with that guy.
Well except when I'm right and he's wrong of course.

Mom? Dad? It's times like these that make me believe you aren't getting a divorce
