With a Sagemcom BCM6846 F@st5684 software version SGCA510000045 (quite a new modem?) I get the below

sander@zwart2204:~/git/miniupnp/miniupnpc$ build/upnpc-static -l

Let's continue with -i ignore:

That 100.64.192.115 is correct, but no further luck.

Let's try -L

Let's try that first URL ... which goes OK:

... good.

Let's try that second URL:

                                 404 Not Found

Not good.

Wait ... if I ignore the errors, it seems to work:

GetGenericPortMappingEntry() returned 713 (SpecifiedArrayIndexInvalid) is ok if the index is indeed invalid.
