Serviio

Hello. Yesterday I changed my internet company, and they gave me a ZTE ZXHN F6640 router. Since I have it on I can no longer access the service on my 2016 samsung, which with my previous router from the other company I did not have to configure anything and only the app came out directly on my TV (DLNA).
What do I have to configure in my new router to be able to continue using the service (DLNA) in my old samsung tv? All the best!!!.

I can't find a manual online for that router, so I can only make some assumptions. Are all your devices connected via WiFi, or is there some Ethernet mixed in as well? Since the router is the only change made, it must be a setting in the router. Look under the WiFi security settings for something that is labeled block internal access or anything that implies that connected devices cannot see other devices on the network.

Hello, thanks for answering me. I only use network cable connection, never Wi-Fi, I don't like Wi-Fi. I have put photos for you to see the ports that I have opened, and where it says "PC IP" is the personal computer (where the SERVIIO is installed) and the IP of the personal computer. I can't get it to work, this is frustrating.

Problem solved, call the technical service of my company and they solved the problem, thanks.

First, you have no need to port forward anything for Serviio to work within your home network. Port forwarding 1900 and 8895 does nothing, as DLNA packets are not supported across the public Internet. The other port forward, for 23424, is for MediaBrowser. If you have purchased a Serviio Pro license, then you would forward that port to access MediaBrowser from the Internet. But again, it's not needed for internal use.

I'm glad your ISP resolved your connectivity issue. But please remove the unneeded port forwarding in your router, as they open potential holes in your firewall for no purpose.
