Been struggling with this for a couple of days now.
I have an EC2 instance on AWS with two network interfaces. Both have separate Elastic/public IPs assigned to them.
The problem is that I can subscribe and publish to the private IP of the broker bound to one of the interfaces but not the public IP. Inbound ports are open and no other firewall present.
have searched the web but the only solutions suggested was to remove the IP and put a listener on port only. This will not work for me since I have to specify one of the network interfaces to avoid port conflict with the other network interface.
The listener row in config looks like this:
listener 8883 <private_ip>
If I put the public IP there instead, I get the error message "Error: Cannot assign requested address", probaby since the interface is assigned to the private address and not the public.
Any idea on how to solve this?
