Troubleshooting Mode:

The Troubleshooting Mode window displays when Troubleshooting is selected from the Diagnostics menu in the navigation panel. This window is used if the server is not sending or receiving packets as normal.

WARNING: Note that when using this tool system resources are utilized, impacting the Web Filter’s performance. When you click Enable the Web Filter will stop filtering the network. After you finish making the necessary changes to the server, be sure to click Disable to terminate your Troubleshooting Mode session. Once Disable is clicked, the Web Filter will resume filtering the network.

Packet Logging frame
1. 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.

2. 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—LAN1 or LAN2.

NOTE: On a mobile Web Filter running software version 5.x.xx, the "LOOPBACK" option is available in this menu and displays by default.

3. 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).

If necessary, click the appropriate radio button to indicate whether to turn the promiscuous mode on or off. If on is selected, the Web Filter will watch all network traffic as in the invisible mode. If off is selected, the Web Filter will only capture packets sent to or from the Web Filter.

NOTE: See the Operation Mode window for more information about the invisible, router, and firewall modes, and listening devices.

4. 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 Web Filter; packets sent to or from port 20 or 21; or packets to the Virtual IP address’s port 137 or 139.

NOTE: On a mobile Web Filter running software version 5.x.xx, the option "Packets to (mobile server) port 3128 or 3129" is also available.

5. Click Execute to display results in the Result list box.
