Trying to get a solid answer on whether or not traffic that is using only the prefilter bypasses CPU cycles. I'm getting different answers on this.

I have my local Endpoint set to Bidirectional connection type, but it is not able to originate or initiate connection with the remote node. How do I set it to be the initiator? This is FirePower FTD.

Connection Type
Specify the allowed negotiation as bidirectional, answer-only, or originate-only. Supported combinations for the connection type are:
Remote Node | Central Node |
Originate-Only | Answer-Only |
Bi-Directional | Answer-Only |
Bi-Directional | Bi-Directional |
Table 1. Connection Type Supported Combinations |
This is the only guide I have and its not actually serving my needs. Any help?
