Problem Description
Added vFW to the VM and tested the policy of blocking all traffic, after applying it the test found that it was still able to ping other VMs.
Filtering policy for vFW is not in effect.
Process Analysis
Check if the Data Passthrough feature is turned on, according to the user manual, if this feature is turned on, all traffic will be passthrough with a higher priority than the vFW's policy.
