To prevent devices connected to the eSAM from using it as a gateway, we will be disabling the Masq (also
called the Masquerade) service running on the eSAM. This service advertises to devices that are connected to the
eSAM that it has access to the internet, and that it should be sent any packets connected devices want to send to the
internet.
Once this function is removed, connected devices will not be aware that the eSAM is an internet gateway and so will
not send it any internet packets
1. Send the eSAM the SMS command ‘masq;delete;modem’
This command will remove the modem interface from the list of masq interfaces. Please wait until receiving a
confirmation message from the eSAM, as sometimes it will take time for an SMS message to be transmitted
depending on the network quality.
2. Once you have received the ‘Masq delete success’confirmation message, send the eSAM the SMS
command ‘reboot;’. Rebooting the modem will cause any connected devices to reconnect once the modem
comes back online, at which time they will notice that the modem is no longer running the Masq service.
3. Wait while the modem reboots. Once the modem restarts, you will be able to access the modem using its
Web Interface, but any connected devices will lose their connectivity. The below log shows the status of a
device trying to ping an online server while this process takes place.
