UPnP & NAT-PMP SSDP Bug
I recently changed an existing pfsense router's interface to a different subnet binding and address. I noticed a few weeks later looking at wireshark captures that the pfsense box was sending SSDP NOTIFY for the UPnP feature using the old IP address still. A simple disable/re-enable of the UPnP configuration immediately cleared up wireshark to start showing the correct address.
Is this a known bug in pfsense not updating the UPnP service or reloading its configuration when an interface IP address has changed? This occured on 2.4.4-RELEASE-p3.
