The environment does fulfil the assumptions necessary for replication to happen 
within the handshake so under 3.2 there is no issue with handshakes completing 
under an asymmetric path.

Nonetheless, what doesn't make sense is that this operates under 3.2 and not 
3.4 - also is the fact that having a "-j CT --notrack" on specific traffic (i.e. 
asymmetric should not matter because there is no stateful tracking)

Kind Regards,
Oliver
