Need advice on a network solution for our organizations.

So... this is my first post here and if it's in the wrong subreddit sry for that.

We are trying to update/redo our organizations networking to make it easier to maintain and to future proof it. Right now, we have old windows server acting as our DHCP and DNS for our subnetwork which is not ideal since it’s it version of windows is EOL… The university supplies us with the subnetwork and handles the gateway and firewall between our subnetwork and the rest of the universities network.

There are two main problems we have:

1. The ones that are handling the network volunteers (students) and may change on an annual basis, so the solution needs to be easy to maintain and to configure.
2. We are limited by in how we can use the network due to university network rules and the physical structure of the network.

- So, we are not allowed to set up the network in such a way that nodes are hidden from the university. (i.e. we can’t have our clients behind a NAT)

- And we can’t really set up any device (physically) between the university’s switch and our clients.

The solution needs to:

- Be standalone and commercially available (not a homebuilt server)

- Be able to be a DHCP for our subnetwork provided by the university

- Option for network boot server configuration

Features we would like (not needed) are VPN, Firewall, DNS, Traffic analysis / package inspection.

I started by looking at ubiquiti’s gear like the USG pro but found out that it can’t be allocates to a ip range and have its NAT turned of out of the box (at least not without reconfiguring the json which I heard can be a pain in the ass to do). So now I am a bit stuck in were or what to look at. I know what functions we need and what we what, but I can’t really figure out what to search for…

Is there anyone that can help me out/point me in the direction I should look for a solution?
