I have configured a Google Cloud NAT setup with two egress IPs and running a GKE private cluster. One of the egress IPs is functioning correctly, but I'm unsure about the usage or purpose of the second egress IP. How can I determine which traffic is routed through the second egress IP and whether it's being utilized effectively? Are there any specific monitoring tools or techniques I can use to analyze the usage of each egress IP in my Cloud NAT setup?
Also I notice when I exec into any pod and curl http://ipecho.net/plain then it return 1 cloud nat egress IP but what is the use of cloud nat 2nd IP?
Any insights or suggestions would be greatly appreciated. Thank you!
