Description
When performing ping test through FortiGate slave unit, it is observed that the ping failed, and debug flow is printing the message 'local-out traffic, blocked by HA'.

Solution
1) When attempting to perform a ping test from the slave unit, the ping failed

# execute ping 10.10.10.1
PING 10.10.10.1 (10.10.10.1): 56 data bytes
sendto failed
sendto failed
sendto failed
sendto failed
sendto failed

2) The debug flow is printing the below message:

id=20085 trace_id=3628 func=print_pkt_detail line=5501 msg="vd-root received a packet(proto=1, 10.10.10.10:55136->10.10.10.1:2048) from local. type=8, code=0, id=55136, seq=0."      
id=20085 trace_id=3628 func=init_ip_session_common line=5666 msg="allocate a new session-011b8e62"
id=20085 trace_id=3628 func=fw_local_out_handler line=825 msg="local-out traffic, blocked by HA"

The message 'local-out traffic, blocked by HA' will show up in a debug flow if the unit trying to send (self-originated) traffic out from the HA slave unit.
This is actually by design or expected in A-P scenario.
To resolve the issue, perform the ping test from the master unit instead.
