To make one of your VMs accessible from outside the UGA network, you need to request a port opening with UGA. Indeed, NOVA does not manage this part of the network. For example, to open port 443 (HTTPS) for a website, you must use the dedicated UGA form: https://formulaires-d7.univ-grenoble-alpes.fr/fr/cdc-site-web. For ports other than those dedicated to web applications, contact the IT service of your organization.
