Configuring LAN to WAN Firewall

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.

Port Filtering

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.

IP Filtering

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.
