## Symptoms

- After disabling Implied Rules, and enabling explicit rules for SCV related traffic, tunnel test packets are being dropped on "NEEDS_SCV".

## Cause

The Implied Rules are coded in a way to enable a specific mechanism for the SCV process.  
This mechanism won't be prompted if using explicit rules instead, and the tunnel packets will be dropped:  
"dropped by fw_scv_verification Reason: returning packets on NEEDS_SCV".
