I suggest getting a small office/home office router with which to connect all your devices together. The router's WAN port would then be connected to the University network.
Check with University's guidelines on this matter: installing a WiFi access point may be forbidden, so that feature might have to be disabled on the router, if applicable. Otherwise, there is little or no additional configuration required, except possibly assigning specific IP addresses to each devices' MAC address in the router's DHCP facility.
Some benefits to this approach include having a local private network on which all ports and traffic will be open and unrestricted between the individual hosts, automatic DHCP configuration will place all hosts connected to the router in the same network by default, each host can access the Internet if required through the router, and network traffic generated between the hosts behind the router does not interfere with the University network.
This design is also highly portable: It can be taken to another office, another building, another campus, home, or anywhere else and still work the same, regardless of what network to which the router's WAN port connects, if any.
