Industry Cellular Gateway
"Packet Filter" function can let you define some filtering rules for incoming and outgoing packets. So the
gateway can control what packets are allowed or blocked to pass through it. A packet filter rule should
indicate from and to which interface the packet enters and leaves the gateway, the source and destination IP
addresses, and destination service port type and port number. In addition, the time schedule to which the rule
will be active.
Packet Filter with White List Scenario
As shown in the diagram, specify "Packet Filter Rule
List" as white list (
Allow those match the following
rules
) and define the rules. Rule-1 is to allow HTTP
packets to pass, and Rule-2 is to allow HTTPS packets
to pass.
Under such configuration, the gateway will allow only
HTTP and HTTPS packets, issued from the IP range
192.168.123.200 to 250, which are targeted to TCP
port 80 or 443 to pass the WAN interface.
