 How is this different from the NAT rule?  Well the NAT rule was telling the firewall how to map an external port to an internal one, so that our machine is reachable from the internet.

 pfSense includes built in methods of [[https://docs.netgate.com/pfsense/en/latest/dns/unbound-dns-resolver.html|protection]] against [[https://en.wikipedia.org/wiki/DNS_rebinding|DNS rebinding attacks]].
-In pfSense:
+This protection can prevent being able to connect to a Plex Media Server securely on the local network.
-Navigate to **Services -> DNS Resolver -> General Settings**.
+To remediate this:
-Add the following to the **Custom Options** box on a new line.
+  * In pfSense:
+  * Navigate to **Services -> DNS Resolver -> General Settings**.
-<code>
+  * Add the following to the **Custom Options** box on a new line. <code>
 server:private-domain: "plex.direct"
 </code>
-Ensure that other entries in this box are on separate lines.

+**NOTE: ** An alternative method is to have the following entries within the Resolver Custom option:
+<code>
+server:
+    local-zone: “plex.direct” redirect
+    local-data: "plex.direct 3600 IN A "
+</code>
+</WRAP>
+<WRAP info>
+**NOTE:**  An alternative method to overcome the DNS protection is to navigate to **System -> Advanced -> Firewall and NAT**.
+In **Network Address Translation**:
+  * NAT Reflection mode for port forwards:  **NAT + proxy**.
+While this works for remote connections, it is not everything needed to get local secure connections working, so this is not the recommended approach to take.

+<WRAP important>
+**WARNING:** When working around DNS rebinding protection this way, your apps and Plex Media Server will typically treat the connections as being from a **Remote** source.
+This can affect which streaming qualities are used, as well as trigger Remote-applicable Server Settings - Bandwidth and Transcoding Limits.
