You now have an effective "Deny outbound TCP SYN" rule. This rule
should directly follow the Windows Standard 2000 rule set you added
in step 6. If it does not, highlight the Deny outbound TCP SYN rule
row, and use the arrow buttons to position it directly after the
Windows 2000 Standard rule set.

For more information on creating policies, refer to the section "Creating
Policies and Rules" in the 3Com Embedded Firewall Administration Guide.

Creating a Sample Device Set

Next you will create a sample device set that enforces the policy you created
in the previous section. A device set is a collection of EFW devices that are
associated with a specific policy. You can define any number of device sets and
assign EFW devices to any one of those device sets.
To create the sample device set, follow the steps below.
1 From the Main menu, select New -> Device Set. The New Device Set
window appears.
2 Type Sample in the Device Set Name field.
3 Select the No IP Initiation policy, which you created in the previous section,
from the Policy for the New Device Set box.
4 Click OK. The device set information appears in the working frame.
5 Select a heartbeat interval of 15 minutes from the Heartbeat drop-down
list. (The heartbeat determines how often the EFW devices issue a
heartbeat, or status update, to the Policy Server.)
6 Type Sample device set enforcing the No IP Initiation policy in the
Description field. This field is optional and exists solely to assist an
administrator in identifying the contents of the device set.
7 Click Save.
