Moving the EFW NIC to the New Device Set

Now that you have multiple device sets, you can move the EFW NIC from 
the default device set to the 

No IP Initiation

 device set that you created in 

the previous section by following the steps below.

1

In the Management Console, click the 

Device Sets

 tab in the 

tree-view frame.

2

Click 

Default Device Set

. This device set contains the EFW NIC that you 

added earlier in this guide.

3

In the Device box, highlight the EFW device, and then click 

Move

4

A list of alternative device sets appears. Select the 

Sample

 device set that 

you created in the previous section, and click 

OK

. You will see a feedback 

window indicating that the new policy has been distributed to the 
embedded firewall. The EFW device is moved to the new device set and 
now enforces the new policy.

Testing Policy Enforcement and Viewing Audit Data

At this point you should have an EFW NIC enforcing the 

No IP Initiation

 policy. 

To ensure that the policy is functioning as expected, the following steps 
attempt to connect to the Internet by initiating the TCP protocol HTTP, which 
should be denied by the policy being enforced. You will then view the audit 
generated by the failed attempt.

1

On the machine hosting the EFW NIC, attempt to connect to 

www.3com.com

. If you were denied access to the site, the EFW NIC 

is correctly enforcing the “No IP Initiation” policy. If you were able to 
connect to the site, go back to the “Creating a Policy” section in this 
guide and verify that you correctly set up the policy rules.

2

To view the audit generated by this access attempt using the Management 
Console, follow the steps below:

a

In the 

Audit

 menu, select 

Audit Browser

 (or click the 

 icon). 

b

In the 

Query

 menu, select 

New

 (or click the 

 icon). The Query Editor 

window appears.

c

Type 

All Recent Audit Records

 

in the Query Name field.

d

In the Rule tab, select the 

All Devices 

check box in the For area, and the 

All rule matches

 check box in the Show area.

e

In the Policy tab, select the 

All Policies 

check box in the For area, and 

the 

All policy event

s

 check box in the Show area.
