In this example, where a match becomes a block list firewall entry. The Layer-4 Traffic Monitor matched 
an IP address to a domain name in the block list based on a DNS request which passed through the 
appliance. The IP address is then entered into the block list for the firewall.

172.xx.xx.xx discovered for www.allowsite.com (www.allowsite.com) added to firewall allow 

list.

In this example, a match becomes an allow list firewall entry. The Layer-4 Traffic Monitor matched a 
domain name entry and added it to the appliance allow list. The IP address is then entered into the allow 
list for the firewall.

Firewall noted data from 172.xx.xx.xx to 209.xx.xx.xx (allowsite.net):80.

In this example, the Layer-4 Traffic Monitor logs a record of data that passed between an internal IP 
address and an external IP address which is on the block list. Also, the Layer-4 Traffic Monitor is set to 
monitor, not block.

.

The appliance creates a directory for each log subscription based on the log subscription name. The name 
of the log file in the directory is composed of the following information:

Log file name specified in the log subscription

Timestamp when the log file was started

A single-character status code, either 

.c

 (signifying current) or 

.s

 (signifying saved)

The filename of logs are made using the following formula:

/LogSubscriptionName/LogFilename.@timestamp.statuscode

 

You should only transfer log files with the saved status.
