Differences in firewall zones

English Network/Internet

Hi All.
Can anyone fill me in on what is the difference between the “apparently similar” zones available for the firewall? ie in particular, what is the difference between : internal / trusted / home?
I am trying to connect to DLNA sources on my internal network, and it doesn’t seem to matter which zone I put my wifi in, I still cannot connect to the various media servers unless I actually disable the firewall… Surely if it is a "trusted (generic - ie trusted/home/internal network), these sources shouldn’t be blocked by default?
I know I can individually add ports for various services, but for some (DLNA in particular??), this i also a bit of a puzzle…

Thanks.

Caveat: I have no experience of DLNA and am guessing.

Firewall zones are just a set of pre-named rules that can be configured to suit yourself.
Configure your WiFi network to use a zone (by default it will be “public”

YaST > Security and Users > Firewall
select the zone you are using.
scroll down the list of “Services”.
select “upnp-client” and add it to the “Allowed” list.
“Accept”

Let us know what happens.
