It looks like we have the following two issues:

  1. There are no dedicated mgmt-routes towards the BIG-IQ and DCDs, therefor the DFGW of the tmm-interfaces will be used. This was not visible for us before, because with the older version the BIG-IQ itself was initiating the connections and response traffic was working due to auto-last-hop.
  2. After adding the mgmt-routes for one BIG-IP cluster (for testing) it was still not working due to missing FW-rules. As I mentioned before the direction changed and also we created only FW-rules between the BIG-IQ CM, but not for the DCDs before.

We are currently adjusting these issues and will report back once implemented.

Thank you!
