You can then define Custom Flows. If your applications do not provide Quality of Ser vice
(QoS) control, Custom Flows allows you to define streams for some protocols, por t ranges,
and between specific end point addresses.
• To define a custom flow, click the Add button.
The Custom Flow Entr y screen appears.
• 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 por t 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
por ts. Enter the star ting por t here.
• End Port – Enter the ending port here.
• 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
cer tain 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.
