You can then define Custom Flows. If your applications do not provide Quality of Service
(QoS) control, Custom Flows allows you to define streams for some protocols, port ranges,
and between specific end point addresses.
• To define a custom flow, click the
The Custom Flow Entry screen appears.
• Inside IP Address/Netmask – For outbound flows, specify an IP address on your LAN.
For inbound flows, this setting is ignored. This setting marks packets from this LAN IP
host/network based on the address and netmask information. For outbound flows, the
Inside IP Address/Netmask is the source address. If you enter a zero IP address
(0.0.0.0), the IP address/netmask fields will be ignored.
• Outside IP Address/Netmask – If you want traffic destined for and originating from a
certain WAN IP address to be controlled, enter the IP address and subnet mask here. If
you leave the default all-zeroes, the outside address check is ignored.
For outbound flows, the outside address is the destination IP address for traffic; for
inbound packets, the outside address is the source IP address.
Note:
When setting the Inside/Outside IP Address/Netmask settings, note that a netmask
value can be used to configure for a network rather than a single IP address.

button.
• Name – Enter a name in this field to
label the flow.
• Protocol – Select the protocol from the
pull-down menu: TCP (default), UDP, ICMP,
or Other. "Other" is appropriate for set-
ting up flows on protocols with non-stan-
dard port definitions. IPSEC and PPTP are
common examples.
• Numerical Protocol – If you select
"Other" protocol, this field appears for
you to provide its actual protocol number,
with a range of 0 – 255.
• Direction – Choose Outbound (default),
Inbound, or Both from the pull-down
menu.
• Start Port – For TCP or UDP protocols,
you can optionally specify a range of
ports. Enter the starting port here.
• End Port – Enter the ending port here.
