To define a custom flow, click the Add button. The Custom Flow Entry 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 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 option- ally specify a range of ports. Enter the starting port 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.
