Packet filters allow you to control access to the network (local and Internet) by analyzing every 
inbound and outbound packet. Depending upon the rule you define, packets will be evaluated 
against source address, destination address, service port and time of day/week. Since inbound 
packets are naturally filtered by the router’s NAT firewall, the inbound filters only protect the 
Virtual Servers and DMZ host. 
 
For example, a business may limit Internet resources (including peer-to-peer file sharing, music 
stores and games) during business hours, Monday through Friday. With the powerful allow/deny 
rules, you can make this rule apply to everyone (except yourself). 
 

•  Outbound Filter. Click to enable all the rules defined on this page. 

Select one of the filtering policies: 
1. Allow all to pass except those matching the rules defined in the table. 
2. Block all except those matching the rules defined in the table. 

•  Source IP. Local IP address (typically in the form 192.168.123.100) or range of 

addresses (192.168.123.1-192.168.123.255). 

•  Source Port. Enter a single port (e.g., 80) or a range of ports (1000-1999). To limit the 

port range only to the TCP protocol, add a T prefix (e.g., T80) or U prefix (e.g., U80) for 
UDP. No prefix indicates both TCP and UDP. Leave the field blank to specify all port 
addresses. 

•  Destination IP. Specify a single IP address or a range of addresses. 

•  Destination Port. Enter a single port or range of ports.
