General Discussion / CyberSecurity Project

Hey OPNsense enthusiasts!! I am new to this software and firewall configurations in general, I'm working on a project for my cybersecurity course and I have to structure a network for an ecommerce business.
Okay so I went with a back to back firewall architecture since it provide more security, so inbetween these firewalls there is a DMZ. The structure looks like this WAN - > External Firewall - > DMZ - > Internal Firewall - > LAN
Note that I'm doing all of this in the network of my university and in VirtualBox.
The Virtual Machine with the OPNsense software for the external firewall has a "Bridged Adapter" for the WAN and an "Internal Network" adapter for the DMZ. Since there wont be a LAN interface configured for this firewall it was a bit hard getting access to OPNsense's web GUI but I did it through a shell code. ( Should I configure the DMZ as the "LAN" interface in this VM?)
The DMZ will contain services like FTP and Web Server and Email gateway. (Open to suggestions)
Any firewall rules that I should look for in both the WAN and DMZ interface?
Also how will I connect both external and internal firewall through the DMZ?
Thanks for the help!!
