Figure 80: Add Advanced Filter
The Matching and Operation sections of this screen define the operation to be executed when matching
conditions apply.
3. Use the Matching Section to define characteristics of the packets matching the rule.
Source Address The source address of packets sent or received by the L13. The drop-down menu provides
the ability to specify the computer or group of computers on which you would like to apply the rule. Select an
address or a name from the list to apply the rule on the corresponding host, or click Any to apply the rule on
all L13 LAN hosts.
Destination Address The destination address of packets sent or received by L13. This address can be
configured in the same manner as the source address. This entry enables further filtration of the packets.
Protocol You may also specify a traffic protocol. Selecting the Show All Services option from the drop-down
menu expands the list of available protocols. Select a protocol or add a new one using the User Defined
option. This will initiate a sequence that will add a new Service representing the protocol.
Using a protocol requires observing the relationship between a client and a server in order to distinguish
between the source and destination ports. For example, let's assume you have an FTP server in your LAN,
serving clients inquiring from the WAN. You want to apply a QoS rule on incoming packets from any port on
the WAN (clients) trying to access FTP port 21 (your server) and the same for outgoing packets from port 21
trying to access any port on the WAN.
4. You must set the following Traffic Priority rules in the Operation Section:
