Hello @Markus Embacher,
I have successfully updated the mainframe configuration and now we can drop off files coming from the mainframe to our AWS ec2 instance. However, the traffic from the aws ec2 instance to the mainframe public address seems to be timing out somewhere. Is there any configuration change we need to consider for the traffic going the other way?
I am working with my network team to see if it is just a network issue, but I just wanted to make sure that there are no other application configurations to consider. Again, the file can be dropped off from the mainframe to the AWS private instance now (using the host configuration on the mainframe ini), but the aws private instance cannot drop a file off to the mainframe public instance.
I appreciate all the help you have provided thus far.
