• 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 setting up flows on protocols with non-
standard 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 option-
ally 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/netmask 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.
