Hello,

 

In order to isolate the issue and find the root cause I would recommend to sniff traffic and collect debug flow:

Hi Taher,

 

Please make sure the phase 2 interfaces on A, B and HQ has mapping for required source and destination. Please make sure appropriate policies are available on HQ for traffic from tunnel A to go to tunnel B.
