+#### Status
+
+Gray status shows that we are not currently in the gateway, these port forwarding are being ignored.&#x20;
+
+A <mark style="color:red;">red status</mark> indicates that port forwarding could not be set up automatically. This could be a problem with:

+{% hint style="danger" %}
+* UPnP Nat is not active on the router

+* The port is already taken and cannot be released again.
