Make DNS rebinding optional

Feature Suggestions
1

Since the update that began DNS rebinding my server cannot be connected to from many networks, including the networks that I use at work.
I have seen many articles about other users with similar issues, and some users that need to re-flash or otherwise customize their routers to prevent DNS rebinding protection.

I think there are as many reasons for the DNS rebinding capability as there are reasons against it, for example:

  1. My IT department at work will not disable the protection for any reason
    2)A router may not be owned by a Plex user, thus updating firmware to prevent the protection is not possible.

Can DNS rebinding be made into an optional server setting? Or can it be reversed at the application level?

Thanks.

I think you misunderstood the topic.

‘DNS rebinding’ is not a Plex feature.

A Plex server uses the DNS system in a way, that will often be detected by routers/firewalls as a ‘DNS rebinding attack’ and so, will get suppressed.
However, this is only affecting Plex clients which are in the same local network as the server.
If all your Plex clients in your home network can reach your own Plex server, ‘DNS rebinding protection’ is not your issue, anyway.

Trouble to access your server from remote, e.g. from work has nothing to do with ‘DNS rebinding protection’.
Disabling it at work won’t help you to reach your home server – at all.

You can read more about Plex’s way of using the DNS system and why it does this here: https://support.plex.tv/articles/206225077-how-to-use-secure-server-connections/

More likely reasons for your troubles:

  1. the networks of your users (including your work network) are using a DNS resolver which doesn’t work (well) with the .direct top-level-domain.
  2. some (corporate) firewalls use a blocking list which has “video streaming sites” on it. plex.tv may be on this list.

It is worth a try to disable ‘secure connections’ on your server.
Further diagnosing and possible solutions are not a topic for this subforum.

I will now close this thread, to give back the votes to the users who voted on this thread.
