I have 2 servers in different AZones in one region, they make an outgoing connections to my clients. Right now each server have it own Elastic IP, and an IP address from internal subnet for each AZ. (First AZ - 172.30.0.0/20, Second AZ - 172.30.16.0/20)
My goal is: make a NAT gateway, so all outgoing connections from these servers (in two AZones) goes thru NAT with one Elastic IP. As i understand right now - i can create NAT gateway only in one AZ, since i should choose Subnet.
Question: Is it possibe made a NAT gateway work with two subnets (in my case - two AZ)? Maybe i should create separate Subnet?
Please, help. Thanks in advance!
