    I checked BIG-IP v16.0 and iRules are still the way to go if you want to send a custom HTTP response. There is no functionality to be able to do this from a local traffic policy.

You could try adding a rule specifically for the port 8686 traffic before default_deny_rule and set the action to Ignore. That should allow the connection to continue on to layer 7 where I'm guessing your iRule is sending the external monitor response on the HTTP_REQUEST event. Something like: If TCP port is 8686 at client accepted time, ignore. Since you've masked the ports for the other rules, it is hard for me to tell whether or not one of those rules would catch the port 8686 traffic first.
