When you configure the appliance in the inline network configuration, the appliance enters bypass mode if it cannot function or is turned off. In bypass mode, Internet traffic is routed through the LAN port and the WAN port, but no monitoring or blocking occurs. For bypass mode to function properly, ensure that you use the proper type of Ethernet cables to connect to the LAN. LEDs on the back of the Symantec Web Gateway appliances indicate bypass mode if it is not turned off.
To test the bypass mode
In the Web GUI, click Administration > Configuration > Operating Mode, and then uncheck Service Enabled to disable Symantec Web Gateway.
When you disable the service, Symantec Web Gateway is in bypass mode.
