Can Serviio/ffmpeg bypass router security?

LucianH

I have Win 7 64 running a Serviio DLNA Server (v1.1). The router I am using is a Technicolor TG582n.

I have set up the Router to use "WPA-PSK Encryption" and only "allow New Stations via registration". As such all the "detected devices" listed on the Router are owned by my family and are ones I've actively registered.

The reason for this post is that last night I had a warning (via Norton 360) of high CPU usage from ffmpeg.exe. I believe that ffmpeg.exe is used by Serviio (for transcoding?). The usage peaked at 95% and when monitored via task manager typically was using 25%. At this point, I was the only person on the computer and only using it for browsing.

When I checked Serviio console, I noticed that there were two devices with IP addresses that did not match any of the devices allowed on the Router.

My immediate concern was whether someone was accessing my DLNA server without my knowledge.

So I have few questions:

1) Why can Serviio "see" devices that are not allowed by the router and is there different security settings for DLNA access?

2) What other programs could have been using ffmpeg.exe?

3) Is there anyway of monitoring DLNA activity?

If the devices "are not allowed by the router" how are they getting an IP address?
I would first look at the router config to check settings and connected devices.
You can also deny access to any particular device from within Serviio Console.

Personally I would have quickly stopped the Serviio server and listened out for which room the subsequent scream came from!

That's exactly my concern. I've check router settings and can't see anything I'm doing wrong.

I actually killed ffmpeg using task manager and stopped serviio. All residents of the house were accounted for (in the living room). No expletives heard from outide!

What are the devices in question?

OK, I've noticed that I can remove the devices from the Serviio list - which I've now done. I'll report back if any unrecognized devices reappear.

Have you got anything connected to your server via ethernet cable?
"WPA-PSK Encryption" and "allow New Stations via registration" only apply to wireless connections.

I have but they're all accounted for (a TV is connected via ethernet as well as the main PC.
