DNS Rebinding & Permitting a private domain
I have some orbi 850's i need to change the DNS rebinding to allow a domain. Support is zero as its out of warrenty. I cannot find any settings about DNS rebinding protection. Help please. Someo...
I do realize your post is from two months ago, hoping you still might have an interest in this issue from the OP. What the OP is referring to is utilizing a Plex server on your private network to download/transfer content from the Plex server to a mobile device, like an iPad that is also on the same private network.
Getting really frustrating with the "download" function not working very well...
I have also been experiencing this same issue and am looking to resolve it. What I find pretty interesting is I have an identical setup, or very close, to the same setup OP is running:
Orbi Mesh with version V2.7.4.24
CenturyLink Zyxel C3000Z (VDSL "Slow" Internet running firmware CZD005-4.16.011.0)
Per that reddit thread I've linked, explains in detail what those have presumably done to fix the issue. I have change my Orbi DNS to the google addresses for now but I'm still getting the content transfer failures as though nothing was resolved. Seems it is possible the DNS Rebind Protection might be key here but admittedly, I'm not entirely familiar with DNS Rebind Protection and if it effectively isn't in play if I manually set my DNS specifically to something like google.

I was drawn to the specific question of what control the user has over DNS Rebind Protection on Orbi routers, which is zero. There is no user setting.
However, I sense a different factor may be involved. Is the Plex server perhaps connected to an Ethernet switch that is connected to the Orbi router?
At first, the primary question seems absurd. A Plex server and a user device are on the same private network. That seems to be "what Plex is designed for." How could the user device be unable to stream/download content? I could see issues where the user device is remote (on the internet somewhere), but on the same network? No way.
Just by accident, I discovered that some Ethernet switches implement IGMP Snooping, but do not do it very well. When that happens, user devices lose access to media servers that are connected behind a switch.
I would tend to look toward Plex resources to resolve LAN connection issues, such as:

CrimpOnYes, I have an unmanaged switch that is connected between my Orbi and headless MAC mini that is hosting the Plex server. Obviously the iPad is connecting to the Orbi over Wifi and have really not made many changes on the Orbi other than removing/changing security for access control. The only setting I've made which has not left settings as default was manually adding in my own DNS servers, google. As you would know, since the switch is unmanaged, it is basically a "dumb" hub meant to expand the available ethernet connections at the edge.
This whole scenario of persistent content download failures to the iPad from the Plex server on a flat network is most likely predicated from poor internal process of Plex transcoding and handling of the content. The calls are probably not tested well, the server versions seem to update frequently as well as the mobile apps.
Thanks for your thoughts on this.
Can you share the specific model of switch?
DLink DGS-108 - it's an 8-port unmanaged consumer gigabit switch.
I probably didn't explain the situation correctly though. The iPad can connect to Plex and stream content, no issues there. I can also have the iPad successfully kick-off the content download, no issues there. It is when the content is being transferred, a transcoding process is running on the Plex. The content on Plex is typically 1080P at a pretty high bitrate and the original format of the content results in pretty large file sizes. Besides the part of higher res and bitrate are pretty big overkill when viewing direct on the iPad, I don't have a lot of space, so transcoding the content into something like 720P at 2-3mbps is plenty quality wise and allows for more content on my 32GB iPad.
Some may find this dumb, but reasoning behind downloading the content is I go boondocking in central CO for 1 1/2 weeks where there is no mobile signal. I actually transfer fly tying videos, and some movies, and bring all of my fly tying stuff in my travel trailer. The movies are for night or if it decides to rain. Yes, I can get by without downloaded movies during my trip but like to have some of my other videos for difficult patterns I don't tie often.
