Use the Troubleshooting Mode
1. Click Enable to begin working in the troubleshooting 
mode.
2.  In the Packet Logging frame, select the Packet Logging 
Time from the available selections (10 seconds, 30 
seconds, 60 seconds). This time is the interval during 
which the server captures packets in real time, ranging 
from the moment the command is executed until the 
designated point of time in the future.
3. At the Capture Device field, the default listening device 
for the operation mode displays. If necessary, make a 
selection from the pull-down menu that corresponds to 
the operation mode used on the network—”LAN2” or 
“LAN1”.
4. At the Promiscuous Mode field, the default choice (“on” 
or “off”) displays, based on the operation mode that was 
selected. The promiscuous mode is a mode of operation 
in which each data packet that is sent will be received 
and read by the Network Interface Card (NIC).
5.  If necessary, click the appropriate radio button to indicate 
whether to turn the promiscuous mode on or off. If “on” is 
selected, the ProxyBlocker will watch all network traffic 
as in the invisible mode. If “off” is selected, the Proxy-
Blocker will only capture packets sent to or from the 
ProxyBlocker.
6. At the Capture String/Rule field, select the type of 
packets to be captured: Transmission Control Protocol 
(TCP); Address Resolution Protocol (ARP); packets 
destined to a specified port (80, 443, 81); packets 
destined to the ProxyBlocker; packets sent to or from 
port 20 or 21; or packets sent to the Virtual IP address’s 
port 137 or 139.
7. Click Execute to display results in the Result list box.
