5.4.1 Packet Filter

Packet Filter enables you to control which packets are allowed to pass through the router. Outbound filter applies on all outbound packets. However, Inbound filter applies to packets that are destined to Virtual Servers or DMZ host only.

Outbound Packet Filter is the default packet filter page. To change to Inbound Packet Filter, click on the Inbound Filter button.

You can select one of the two filtering policies:

1.Allow all [packets] to pass except those [that] match the specified rules

2.Deny all [packets] to pass except those [that] match the specified rules

Check on the Enable box to activate the packet filter function.

You can specify up to 8 filters for each direction. For each rule (ID), you can define the following parameters:

Source IP address

Source port address

Destination IP address

Destination port address

Protocol: TCP or UDP or both.
