“Two” interesting concepts on Cloud NAT...| Whitelisting & On-Demand NAT External IP

Cloud NAT (network address translation) lets Google Cloud virtual machine (VM) instances without external IP addresses and private Google Kubernetes Engine (GKE) clusters send outbound packets to the internet and receive any corresponding established inbound response packets.

Very good explanation

[@LearnGoogleCloudwithMahesh]

Thanks Nandita

[@ericksonjosephsantos8857]

Very good explanation, I really appreciate this demo as I am a network guy shifted to cloud computing. You are really good at explaining small stuffs that matters especially in a network engineer point of view. Looking forward to learn more from you.

[@LearnGoogleCloudwithMahesh]

Thanks Erickson

[@shaileshchaskar6093]

Thanks for this video - a valid point. On Demand was interesting from cost effective prespective.

[@ibmuser13]

good one. thanks Mahesh

[@shashikiran5015]

Great and Valuable Content. Would like to see some content on Terraform with GCP. Can you please make a playlist for that particularly.

[@LearnGoogleCloudwithMahesh]

Thanks Shashi...

[@jesusperez7545]

Fantastic!

thanks you

i understood all the creation of the nat gateway and the router, but i would like to know how i can connect to my vm if it doesn't have external ip?
I know it connects to the internet, but I still have to open my website on a cell phone.

[@deepakdamodaran9121]

Great video. For a VM to get an ip address should the region and the VPC network of the cloudNAT/cloud Router match the network and region of the VM ?

[@LearnGoogleCloudwithMahesh]

You can create VM only is subnet in that region exist

[@ambeshsingh1251]

Informative video Mahesh. It would be better if the sound can be little louder. Thank you

[@LearnGoogleCloudwithMahesh]

Sure

[@ramulusuddewar9655]

Hi Mahesh, thanks for providing this info. Is it possible to have single external IP address which is created through Cloud NAT for multiple VM instances, or new external IP will be created for each instance created. Thanks

[@LearnGoogleCloudwithMahesh]

One Nat for one Region

[@ramulusuddewar9655]

thank you 🙏

[@briannkurunungi2837]

Hello Sir, thank you for the great content as you have done always. My question is how my microservices in GCP use whitelisting to communicate to external services. Is there a way for my service to be one to whitelist the external service IPs, not the other way round u gave in example - to give external service my external IP so they can whitelist. Please advise

[@LearnGoogleCloudwithMahesh]

If it is a microservice deployed in Compute Engine/ GKE/ Cloud Run for access those microservice will use Load Balancer. Cloud NAT will be only used if these microservice needs to access outside resources

[@briannkurunungi2837]

@@LearnGoogleCloudwithMahesh Thank you Sir , I thought with a load balancer , I would optimize calls made to me (GKE) app. Is it possible to connect to an external oauth 2 server , and my clients to be non GCP , do u have use case like that Sir?

[@basudebbhanja1144]

it is possible to configure Mikrotik RouterOS inside my EVE-NG which is hosted on my Google Cloud Platform, using Winbox in my local PC.
The standard configuration for the locally installed EVE-NG allows me to connect my PC network to the virtualized network, but since my EVE-NG is now on the cloud, is it possible to connect the RouterOS to my PC Winbox for easier configuration?

[@LearnGoogleCloudwithMahesh]

Apologies, I don't have any exposure on Mikrotik RouterOS

[@mohdt786]

What if I want to whitelist the external IP address for Dataflow service which is serverless, should I reserve a Static IP?

[@LearnGoogleCloudwithMahesh]

Dataflow creates VMs behind the scene which uses VPC. So, IMHO the simple Cloud NAT configuration should do the trick

[@Vneha1705]

Awesome video, consider we've 10 vm in Singapore, so I would imagine all wil use same nat. But in this case if I delete 1 vm will it also delete external ip?

[@LearnGoogleCloudwithMahesh]

Only if all the 10 VMs are deleted NAT IP will get deleted

[@wilmenls]

is the VM also automaticly accessible at Public via Cloud NAT?

[@LearnGoogleCloudwithMahesh]

No

[@abhishekjaiswal4199]

Do i need to create nat for every subnets

[@LearnGoogleCloudwithMahesh]

nat per region in a network is what is needed
