The computer I was referring to is the server I am trying to access.
I've accessed the webpage from my laptop.

There is a strange thing indeed: the server has actually no firewall,
however the 1900 UDP port, which should be open for SSDP seems closed.

Here it is the result of some investigation
---
# On my laptop
$ nmap -sU -p 1900 santini_server
Starting Nmap 7.40 ( https://nmap.org ) at 2017-06-05 11:32 ora legale
Europa occidentale
Nmap scan report for santini_server (192.168.0.109)
Host is up (0.027s latency).
PORT     STATE  SERVICE
1900/udp closed upnp
MAC Address: 00:1E:2A:43:47:3E (Netgear)

Nmap done: 1 IP address (1 host up) scanned in 12.43 seconds

# On the server
$ sudo iptables --list

Chain OUTPUT (policy ACCEPT)

No idea why MiniDLNA does not check the port.
