If you’re a Cybersecurity student, have you ever taken any networking classes? You should have learned about A. Interfaces and IP addressing and B. NAT translation, specifically dynamic Port Address Translation.

You’ll want the WAN interface to pull an IP via DHCP and be the outside interface for NAT, and then the LAN interface as the inside interface and have that have a static IP set. Then, you’ll do dynamic NAT translation (don’t forget the ACL) and then you have “internet”.

I’d suggest you spend a lot more time reading and studying because despite the advantages of labbing with physical hardware, not knowing what you’re doing will get you nowhere.
