Filtering function is used to block packets from LAN to WAN. The device 

supports three kinds of filter Port Filtering, IP Filtering and MAC Filtering. All 

the entries in current filter table are used to restrict certain types of packets 

from your local network to through the device. Use of such filters can be 

helpful in securing or restricting your local network. 

When you enable the Port Filtering function, you can specify a single port 

or port ranges in current filter table. Once the source port of outgoing 

packets match the port definition or within the port ranges in the table, the 

firewall will block those packets from LAN to WAN. 

 

When you enable the IP Filtering function, you can specify local IP 

Addresses in current filter table. Once the source IP address of outgoing 

packets match the IP Addresses in the table, the firewall will block this 

packet from LAN to WAN.
