Explanation and Instruction
After this rule built, gateway will start IP address filtering function. According to running
rule “Receive packet matching following rule”, gateway forbid all data packet to go
through, but only allow protocol data packets (
select “ALL”
) from WAN
“121.204.201.13”
(select “IN/OUT” direction
) to go through PPPO interface (
select PPP0
interface
). Usually this rule shields invalid IP address to go through gateway, can reduce
data flow, or as bank application, can shield other IP address access to bank IP address to
realize filtering functional and reduce data flow.
MAC Address Filter
Rule name
：
it is limited to use characters 0-9.a-z.A-Z
，
also can’t repeat name
MAC
：
Block or permit device MAC address, input format is“00:12:23:34:45:56”
Example 1:
1. If select “setup MAC address filtering”
2. Running rule select: “discard packet matching following fule ”
3. Input“00:00:23:34:45:56”in MAC.
So gateway will discard all data packet of MAC address “00:00:23:34:45:56”,
meanwhile permit all data packet which MAC address is not“00:00:23:34:45:56”to go
