Chapter 3 Configuration

 Outgoing      Incoming: Determine whether the rule is for outgoing packets or for incoming packets. 
Active: Choose “Yes” to enable the rule, or choose “No” to disable the rule. 
Packet Type: Specify the packet type (TCP, UDP, ICMP or any) that the rule will be applied to. 
Select TCP if you want to scope for the connection-based application service on the remote server using 
the port number. Or select UDP  if you want to scope for the connectionless application service on the 
remote server using the port number. 
Log: Choose “Yes” if you want to generate logs when the filer rule is applied to a packet. 
Action When Matched: If any packet matches this filter rule, Forward or Drop this packet. 
Source IP Address: Enter the incoming or outgoing packet’s source IP address(es). 
Source Port: Check the TCP or UDP packet’s source port number(s). 
Destination IP Address: Enter the incoming or outgoing packet’s destination IP address(es). 
Destination Port: Check the TCP or UDP packet’s destination port number(s). 
 
If the DHCP server option is enabled, you have to be very careful in assigning the IP 
addresses of filtered private IP range in order to avoid conflicts because you do not know 
which PC in LAN is assigned to which IP address. The easiest and safest way is that the 
filtered IP address is assigned to specific PC that is not allowed to access outside 
resource such as Internet. You configure the filtered IP address manually to this PC, but it 
is still in the same subnet with the router.
