Use any internet connection, you do not need to set up a VPN or Remote connection.
Access to all resources should be the same on and off campus IF you get to Primo after signing in via the DLE or University Portal, using your University computing name and password.
TOP TIP: The authentication system will give you more full text if you go to PubMed and Google Scholar via the 'Find Databases' link at the top of the Primo homepage. (Please note that not all resources are discoverable via PubMed or Google Scholar so it always advisable to also search Primo for results where full text is not available - just in case!).
