Not Subject to NDA
When a packet comes from the IP address incoming_IP, the firewall
chain rules will be scanned for matching with the following criteria:
incoming_IP & <net_mask> = <ip_addr> & <net_mask>
If criterion is matched, then the packet is accepted and the rule
scan is finished; if criteria are not matched for any chain the packet
is silently dropped
AT#FRWL?
Read command reports the list of all ACCEPT chain rules registered in the
Firewall settings in the format:
#FRWL: <ip_addr>,<net_mask>
#FRWL: <ip_addr>,<net_mask>
...
OK
AT#FRWL=?
Test command returns the allowed values for parameter <action>.

Let assume we want to accept connections only from our devices
which are on the IP addresses ranging from
197.158.1.1 to 197.158.255.255
We need to add the following chain to the firewall:
AT#FRWL=1,"197.158.1.1","255.255.0.0"
OK
