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.
