4、Explanation and Instruction
After this rule is built, gateway will start IP address filtering function. According to running rule “Receive packet matching
following rule”, gateway forbids all data packet to go through, but only allows 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 addresses to
access to bank IP address to realize filtering function and reduce data flow.
