Your VPS comes with full access to its operating system, so you manage its firewall from inside the server. On Ubuntu and Debian the easiest tool is UFW:

sudo apt install ufw
sudo ufw allow OpenSSH        # always allow SSH first, or you'll lock yourself out
sudo ufw allow 80/tcp         # web (HTTP), if needed
sudo ufw allow 443/tcp        # web (HTTPS), if needed
sudo ufw enable
sudo ufw status verbose

Locked yourself out? Log in through the noVNC console in the Client Area and run sudo ufw disable.
