Why is there no external access to web servers in the Nginx + Apache bundle?

Question

Nginx

On a remote machine, I use the nginx + apache bundle, the servers start up, but there is no access to them from the outside.
Here are the command outputs:
$ nmap

Host is up (0.00025s latency).
Not shown: 998 filtered ports
PORT     STATE  SERVICE
80/tcp   closed http
8080/tcp closed http-proxy

$ netstat -tlpn

Active Internet connections (only servers)

I see that the ports are closed, but I don’t know how to cure, I don’t really understand, I’ll ask you to give detailed answers. Thank you.
