Hi All,
Below is a picture of my topology,
The file to the packet tracer is also attached. All password or logins are admin and cisco.

I would like DEV and Management network traffic to route through the firewall when access the corp network.
I have yet to configure the router and firewall as i'm not sure in what to do.
My other question is VLAN 10 and 20 can not cross communicate. This is the way i want it, but should i also put ACLS to reinforce this rule as best practice?
Kind Regards,
Daniel!
