NAT Example about aws-transit-vpc HOT 3 OPEN

+1

I am also looking for a NAT example or clarification on whether the CSR 1000v is intended to already NAT requests? I'm currently using this Transit VPC to connect multi-VPC workloads into an on-premises network.

The Lambdas and Detached Gateway approach from Appendix D worked perfectly for route propagation, but given that our on-premises network team doesn't allow for multiple CIDR-block ranges for organizations connecting to their CGW, we find our selves in a situation where if we do not NAT the requests, they die at the CGW without a route home.

I think I found a sample configuration for Cisco CSR NAT setup in the IOS shell (thank you AWS Support Team!), but the bigger question I have is whether or not this quickstart and set of AMI's for the CSR was already intended to account for NAT? If so, I'd assume something is missing in the guide or our implementation, such as the specification for a RouteTable entry or configuration of an attached ENI.

Any guidance or direction here would be incredibly helpful!

Thanks for sharing your feedback. This was included to the solution doc roadmap so we can provide more information about this scenario.

Is the sample configuration file you've (@mark-schaal) mentioned is sharable btw?

Thanks @hvital , unfortunately I've transitioned roles/organizations since I originally wrote this ticket, I no longer have access to my notes on how I resolved the issue from the Cisco IOS. I'll do a quick search through my google history later today and see if anything triggers a memory for me.
