The Firewall enables you to control what packets are allowed to pass the

router. Outbound filter applies on all outbound packets. However, Inbound

filter applies on packets that are destined for Virtual Servers or DMZ host

only. You can select one of the two filtering policies:

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

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

You can specify 8 rules for inbound or outbound. For each rule, you can

define the following:

•

Source IP address

•

Source port address

•

Destination IP address

•

Destination port address

For source or destination IP address, you can define a single IP address

(e.g., 4.3.2.1) or a range of IP addresses (e.g., 4.3.2.1-4.3.2.254). An empty

fields implies all IP addresses.

For source or destination port, you can define a single port (e.g., 80) or a

range of ports (e.g., 1000-1999).

Each rule can be enabled or disabled individually.

Inbound Filter:

To enable the Inbound Packet Filter, click the check box next to Enable in

the Inbound Packet Filter field.

Outbound Firewall: (to access the Outbound Filter, click Outbound

Firewall at the bottom of the window.)

To enable the Outbound Packet Filter click the check box next to Enable in

the Outbound Packet Filter field.

Follow the same procedure as for the Inbound Firewall. The IP addresses

that you input will be blocked from the port activity that you input (e.g.,

browsing the internet, receiving mail etc.)

After Outbound Packet Filter setting is configured, click the Apply button.
