After Virtualmin installation : Forward ports for Portainer and additional Docker

Good day,

I just installed Virtualmin on my Ubuntu server, unfortunately I no longer have access to my Docker containers including Portainer. But they are all still running. I assume that it has to do with the firewall. How can I release the ports?

You should use Networking ⇾ FirewallD module to open needed ports.
