zxkane / snat Goto Github PK

Thanks for the library! I was using the Terraform version, but switched my infra as code to CDK, so this has been super helpful.

Can we include an option to specify the machine image? I'd like to use ARM AMIs.

❓ Allow List IP - Third Party Service

Hi, I need to provide a third party a list of allowed IPs from which to filter my requests.

Therefore, my AWS lambdas need to run within those IPs in order to communicate with the third party service.

I am currently solving this problem with a VPC with a NAT Gateway with one associated EIP. (cannot associate more EIPs to the same NAT)

The problem is that as I scale, I really need multiple EIPs associated with the NAT, and then to have my Lambda function randomly assigned to one of the static IPs from the list of allowed IPs, every time they got invoked (even the same IP twice is fine, but ideally long-term I want to rotate between all IPs of the subnet).

Do you think snat could be useful for this use case? If yes, how?

Thank you very much for the work done.
