Firewall Protection and Content Filtering

6-11

As you define new rules, they are added to the tables in the Rules menu. For any traffic attempting 
to pass through the firewall, the packet information is subjected to the rules in the order of the 
entries in the Rules Table, beginning at the top and proceeding to the default rules at the bottom. In 
some cases, the order of precedence of two or more rules may be important in determining the 
disposition of a packet. The Move button allows you to relocate a defined rule to a new position in 
the table.

Use the Options checkboxes to enable the following:

If LAN users need to use VPN (Virtual Private Networking) software on their computer, and 
connect to remote sites or servers, enable this checkbox. This will allow the VPN protocols 
(IPSec, PPTP, L2TP) to be used. If this checkbox is not checked, these protocols are blocked.

•

Drop fragmented IP packets 

If checked, all fragmented IP packets will be dropped (discarded). Normally, this should NOT 
be checked.

•

Block TCP flood 

If checked, when a TCP flood attack is detected, the port used will be closed, and no traffic 
will be able to use that port.

•

Block UDP flood 

If checked, when a UDP flood attack is detected, all traffic from that IP address will be 
blocked.

•

Block non-standard packets 

If checked, only known packet types will be accepted; other packets will be blocked. The 
known packet types are TCP, UDP, ICMP, ESP, and GRE. Note that these are packet types, not 
protocols.
