Block DLNA access from a wired device
Hi, I have my ReadyNAS connected to a Netgear ProSafe Plus switch. The Switch is connected to a Netgear R7000 router. I also have a snart TV connected by cable to the switch. I want to stop ...

If I block the TV in router access control, only TV access to internet is interrupted. It still can browse the DLNA server
I tried to connect the TV directly to the router instead of the switch, but it is still accessing the DLNA
I didn't try to plug both TV and ReadyNAS directly on the router. However, I don't understand why the Netgear router is still allowing LAN access to the TV
I guess the short answer that is the way the access controls in the router work. In any event, generally the traffic between your TV and your NAS won't even reach the router, it will stay on the switch. When I am watching a video saved on my NAS, I can power down the router and the video continues to play normally.

Is there any way with my network setup to disable the wired LAN TV from accessing the ReadyNAS DLNA server ? Unplugging the cable is not a solution in my case, obviously.
You could connect a second router between the TV and the switch. That would block all services and devices on your network from reaching the TV unless you forward ports - just like your main router.
I'm wondering why you are wanting to do this.
I have a room with smart TV that can be connected to a wall LAN port in the home
I am trying to restrict access to the DLNA server from that device

Are you saying that you have a different DLNA server you want the TV to use? Or that you want to block all DLNA from reaching that TV?
Is it ok completely block the TV from accessing any device on your local network (limiting it to internet only)?
Are you wanting to block the service 24x7, or only for specific hours?
Presumably there are other devices that you want to allow access to ReadyDLNA?
I am guessing that the goal here is parental controls - if not, why are you wanting to block access?
Yes, it is parental control
I have one DLNA server (ReadyNAS)
The TV have a built in parental control and timer for channels, but not for accessing media servers
The TV is connected through LAN, not wifi. I can connect it through wifi but it slows down a bit on some movies
TV accessing the internet is not somnething I am concerned for now. It is more the LAN access to the DLNA server
I see two options that could suit my needs:
- a quick way to toggle the DLNA server on the NAS using a smartphone or some SSH commands vi Android. However, in my last tests, toggling the DLNA server in GUI triggers a rebuild of the whole database, so it will take time before the TV can read the media contents. I didn't test if this issue I had reported previously is still present in recent OS builds
- a quick way to toggle any access from the TV to the LAN.
Netgear Genie sounded a good option to block the TV on the go. However, as you explained, the LAN traffic is always going through the switch even when the TV is directly connected to the router. This is clearly a limitation in Netgear consumer routers I guess. Wired traffic is not blocked at LAN level, only to WAN. If the TV was connected via wifi, this router limitation won't be present.
I can disable ports in the Netgear switch, but it needs a PC with proper software, so not a quick easy option
I can manually plug/unplug the TV LAN cable from switch side, but my switch is not easily accessible
I imagined connecting the TV LAN cable to a second switch. I can turn on/off electric power of that switch using a remote control I already have. I have a spare Netgear GS105E switch that could do the trick. I just wished something simpler
Any ideas?
