When Symantec Advanced Threat Protection: Network (SATP:N) Virtual Edition (VE) or Symantec Web Gateway (SWG) VE enters bypass mode, the appliance does not relay traffic from one inline interface to the other. Network traffic is halted when the service is disabled, the physical host computer is turned off, or the guest VM is powered down.
Virtual Editions of either SWG or SATP:N do not have access to the specialized bypass NICs that are included with physical SWG or SATP:N appliances. Therefore, SWG VE and SATP:N VE both use generic virtual nic device drivers, which will not relay traffic from one interface to the other when the service is disabled, when the guest VM is powered down, or when the physical host is off.
Note that because of this functional limitation, support for INLINE mode of SWG VE is best effort at Symantec Technical Support.
