A week ago, Leila and Charles visited Site 1 to find the DSM inop. For simplicity sake, this past Sunday (4/26) I had them replace the S1 DSM with the unused S9 DSM. Nothing was swapped between the two, so S9 has it's original cell modem and SD card.
eth0- 192.168.1.209 (DSM address)
eth1- 18.104.22.168 (cell modem address)
