I am using a UPnP client (ZeroTier One) that is causing the router to send a perplexing error message. The following error is sent back when the client tries to setup a mapping:
<UPnPError xmlns="urn:schemas-upnp-org:control-1-0">
<errorCode>725</errorCode>
<errorDescription>OnlyPermanentLeasesSupported</errorDescription>
</UPnPError>
Has anyone else experience similar problems?
The UPnP interaction between the client and the router:
