Ip Filter - Huawei EchoLife HG520 User Manual

4.4.6 IP Filter

IP Filter is a software package that can be used to provide
network address translation (NAT) or firewall services. It restricts the
IP address of a computer or the IP address of a segment to access the
Internet via certain ports.
If the IP filter feature is activated, it allows/rejects the packet from
a specific port of a specific IP address to be forwarded to a local
specific port of a specific IP address. Take Figure 4-27 as example,
the packets from port 100 to port 200 of IP address 10.132.41.120 are
not allowed to be forwarded to local port 100 to port 200 of IP address
192.168.1.100. You can add you own rules based on actual needs.
