You need to disable Detect Protocol in the Visual Policy Manager (VPM) for ProxySG or Web Security Service in Universal Policy Enforcement (UPE) Mode.

You may need to complete this action if a Symantec Support has advised you to do so.

  • Web Security Service (only in UPE Mode)



Please do the following in VPM

  1. Create a Web Access layer
  2. Select a Source and Destination
  3. Under Action: Set > New > Disable SSL Detection > All Tunneled Traffic
