Description
This command allows you to configure the mask to limit the IP addresses that may
establish a data connection with the device.
This command is only valid if the “AT*Z17=0” command indicates server mode.
This command format is similar to an IP address. In this case the IP address for
the incoming TCP/IP session is “filtered” with this mask and if it doesn’t pass the
filter, the connection is dropped.
