MiniDLNA server needs UDP port 1900 open on firewall

MiniDLNA_server_needs_UDP_port_1900_open_on_firewall.md

Issue:

Latest version of VLC on Linux and Windows 10 did not see miniDLNA server on my CentOS 7 machine.

Solution:

Determined that TCP port 8200 and UDP port 1900 need to be open on my CentOS 7 server. I was missing the UDP port.

firewall-cmd --permanent --add-port=1900/udp
firewall-cmd --permanent --add-port=8200/tcp
firewall-cmd --reload
firewall-cmd --list-all

Don't forget the client

Discovered that UDP port 1900 must be open on the CLIENT machine also. On my Fedora 30 system, the following commands did it for me. VLC was able to disover my MiniDLNA server.

[kurtis@xps15 ~] $ sudo firewall-cmd --permanent --add-port 1900/udp
success
[kurtis@xps15 ~] $ sudo firewall-cmd --reload
success
[kurtis@xps15 ~] $ sudo firewall-cmd --list-all
