Cisco Cisco Web Security Appliance S170 사용자 가이드

When the L4 Traffic Monitor is enabled, you can configure how it should manage traffic over the 
configured TCP ports. It can perform the following actions on traffic over the TCP ports:

Allow

Monitor

Block

For more information about how the L4 Traffic Monitor handles traffic, see 

The actions the L4 Traffic Monitor takes depends on the L4 Traffic Monitor policies you configure.

Navigate to the Web Security Manager > L4 Traffic Monitor page.

Click Edit Settings.

On the Edit L4 Traffic Monitor Policies page, configure the L4 Traffic Monitor policies described in 

Allow List

Enter zero or more address to which the L4 Traffic Monitor should always allow 
clients to connect. 

Separate multiple entries with a space or comma. For a list of valid address 
formats you can use, see 

Entering a domain name such as example.com also matches 
www.example.com and hostname.example.com.

Connections to all destinations in this list are always allowed and the traffic is not 
logged. The appliance does not check the destinations against the L4 Traffic 
Monitor anti-malware rules or the additional suspected malware addresses listed 
on the same page.

For example, if IP address 10.1.1.1 appears in both the Allow List and the 
Additional Suspected Malware Addresses fields, then the L4 Traffic Monitor 
always allows requests for 10.1.1.1.

Do not include the Web Security appliance IP address or hostname to the 
Allow List otherwise the L4 Traffic Monitor does not block any traffic.
