We got z/OS  with multiple TCPIP-Stack

The preffered TCPIPA is denoted as X.X.X.X 
The agent always connects to Stck TCPIP denoted as Y.Y.Y.Y

Environment

Release : 12.3

Component : AUTOMATION ENGINE

Resolution

The issue was resolved by updating the following parameters in the agent INI

bindAddr =
IP address the component uses to connect.

Use this parameter if the connection should be established via a particular IP address (for example, the computer has more than one network interface card).

(HOSTS)
Overwrite IP destination in case of IP NATing problems
(e.g. firewalls)
= or
=

So you can add this entry under HOST section and give the IPAddress or dns name then the IP address used with this address and not the one with which the agent was started.
