I am new to google cloud,
I have been able to setup 1-to-many NAT but need to setup 1-to-1 NAT in google cloud? How do I do this!??! I cannot find the proper documentation, or figure out ... What steps do I need to do to assign an external ip, to an internal ip, and setup the internal ip.s etc. for a single vm.
Google Compute Engine does not provide a service that offers 1:1 NAT so you'd have to build this yourself.

I want to ask a conceptional question and take advices about possible system design if possible.
The plan is basically authenticating specific Gmail users to use my serverless backend application. I'm thinking about either forwarding users directly to my VPC or I can authenticate them in my host-provider server and then after forward them to the VPC (or directly Cloud Run service?).
I'd be really glad if someone experienced can lead me about concepts and suggest design ideas about this.
As commented by#John Hanley, your question has concepts that do not exist.
To invoke Cloud Run authentication to specific users to use your serverless backend application, go through below required possible systems designs :
1)Initially design how to describe IAM roles that are associated with Cloud Run, and list the permissions that are contained in each role.
2)Design how to secure and Configure Cloud Run to limit access to Cloud Run service with Identity aware Proxy(IAP).
3)Design how to create a Serverless VPC Access connector and also know how to use IAP for TCP forwarding within a VPC Service Controls perimeter.
4)Step by step implementation of how to use IAP to secure portal access without using a Virtual Private Network (VPN). IAP simplifies implementing a zero-trust access model and takes less time than a VPN for remote workers both on-premises and in cloud environments with a single point of control for managing access to your apps.
Solution to the what I had in mind was could be accomplished by Identity-Aware Proxy.
Using a Partner Interconnect I'm trying to get the restricted.googleapis.com access to work and having some issues.
The BGP sessions needs to advertise 199.36.153.4/30 for that to work. Does it also need to advertise all the VPC networks? Just the region cloud router is in? None of them?
GCP allows you to advertise the 199.36.153.4/30 network on the cloud router, and it will apply for all the BGP sessions it has, or you can do it for specific ones. It depends on your needs. You only need to advertise this network in order to be known for your on-prem devices which need to know that network.
Consider that you need to define a static route for this same network for your VPC whose next hop is the default internet gateway in order to have that traffic forwarded to the correct destination. For your VMs you need to set firewall rules to allow egress/ingress traffic for this network.
If you require to refer to restricted.googleapis.com from the on-prem network, you can define in your on-prem DNS system A/CNAME records as needed.
You can read more about these topics here and here.
Configuring a VNet-to-VNet connection is the preferred option to easily connect VNets if you need a secure tunnel using IPsec/IKE. In this case the documentation says that traffic between VNets is routed through the Microsoft backbone infrastructure.
According to the documentation, a Site-to-Site connection is also possible:
If you are working with a complicated network configuration, you may prefer to connect your VNets using the Site-to-Site steps, instead the VNet-to-VNet steps. When you use the Site-to-Site steps, you create and configure the local network gateways manually.
In this case we have control over the configuration of the virtual local network address space, but we need expose public IPs. Documentation don´t says nothing about where the traffic goes (azure internal or public internet)
My question is, in this scenario, S2S between VNets, the traffic is routed through azure infrastructure as in the case of VNet-to-VNet or the comunication is done through public internet?
edit
The traffic in an S2S between VNets is routed through Microsoft backbone network. See this doc.
Microsoft Azure offers the richest portfolio of services and
capabilities, allowing customers to quickly and easily build, expand,
and meet networking requirements anywhere. Our family of connectivity
services span virtual network peering between regions, hybrid, and
in-cloud point-to-site and site-to-site architectures as well as
global IP transit scenarios.
There are two servers:
Local Server
behind a firewall (DSL Router)
connected to microcontrollers (actors & sensors)
Cloud Server
sends commands to Local Servers
The idea is that the Cloud Server sends commands to the Local Server. E.g. to trigger an actor. If there was no firewall, the best way would be IMHO to have a REST API on the Local Server. Unfortunately configuring a NAT is not an option.
What is the simplest and most common way to solve this?
Your other options are:
a) pulling, webrequest from local to online server.
b) service bus, also a pulling pattern but with a queue (i.e. Azure Service Bus or Event Hub in example)
c) server of manufactor, sometimes there is already a online service ready, like meethue-API for the hue Philips IoT Lamps
Let me know if you need more hint's.

Our product has software-managed virtual networks and has multiple local IP addresses from which network communications could be routed. One of the requirements we have is to ensure that outgoing traffic is routed from a specific, desired local IP when communicating with the Azure blob storage endpoint.
The Azure SDK does not seem to expose any means of specifying which local IP address to use for communications to the Azure blob endpoint. Please let us know if you think the SDK does expose and if so how we can utilize the facility.
If not, we are evaluating making changes to the azure-storage-java SDK source in order to support the local IP binding requirement.
Has this kind of situation been brought to your attention before? Do you have any suggestions as to how this might be accomplished?
Thanks,
Sowmya.
