Its not the firewall

How do other folks go to prove that its not the firewall but your mgmt team does not believe you? We just had an issue were we had rules in place to route traffic through our main firewall. For whatever reason, Azure decided to take the other route to the 2nd firewall and we had no rules in place so faxes would not work. So we added rules and it starting working, then we blocked that traffic to go through main firewall. So everything is 100% again. We basically eliminated the firewall allowing any any any any any, it was wide open and still blamed the firewall. So then I asked why did it take that other route who misconfigured the routes. The vendor says that our firewalls are routing and assinging it a dhcp address. Well mgmt believes them. So how do you prove that our firewalls are not routers or dhcp servers?

Are you referring to incoming or outgoing traffic?

As you mention DHCP it refers to internal devices accessing Internet.

If it is internal traffic you need to figure out what causes traffic from those internal devices to arrive to different firewall from what you expect.
