I'm using the ACI in a private VNET. My problem is, the outgoing ip from this container is not my public IP used in Azure Gateway, is some random ip.
There's some way to fix somehow this outgoing ip from some container using ACI?
OBS: I tested with a public container, I had a public ip to incoming, but for outgoing was different :|
Thanks!
For your issue, when you create the ACI in the VNET, you just can access the resources inside the VNET and the outgoing IP is a private IP of the VNET, so the IP is static if you do not delete the ACI.
When you create a public ACI, it can access the Internet. This time, as I think, the ACI has two public IP, one is the public IP or the FQDN of the ACI to access from the Internet. And another is the public IP of the host machine that the ACI deploy in. When you access the ACI from the Internet, you need to use the public IP or the FQDN which Azure provide you. But when you access the Internet inside the ACI, the outgoing IP is the host machine's public IP. You cannot decide which host machine you can use, so does public IP of the host machine.
If you need to decide the outgoing IP and must be a static one. You can install the docker server in the VM with a static public IP, then create containers in the VM. Then the outgoing IP is the public IP of the VM.
Or you can use the AKS, create the pod and associated with a service that uses the Load Balancer type. Then the outgoing IP is also static and it's the service public IP.

I have a Virtual Network Gateway setup on my Azure subscription, and a number of VMs which connect to it.
The VN Gateway created a Public IP automatically, and has it listed in the 'Overview' screen.
However going onto any website to check my IP (e.g. whatsmyip.org) gives me an entirely different Public IP. Anyone know why this is?
My configuration of the Virtual Network Gateway is very basic with mostly defaults and the VpnGw1 SKU.
The public IP assigned to the virtual network gateway is a public IP to let you connect Azure VPN gateway from your on-premises network or the Internet.
However, by default, there is a default route to make that Azure VM can continue to accept and respond to requests from the Internet directly. If VM has been assigned a public IP address to the NIC, the outbound traffic from VM will use this IP address. If the VM does not have a public IP address, Azure translates the private source IP address of the outbound flow to a public source IP address. This public IP address is not configurable, cannot be reserved, and does not count against the subscription's public IP resource limit. Read Outbound connections scenario overview.
So the outbound public IP of Azure VM is different than the virtual network gateway public IP.
I want to provision a VM which has no public ip so it can only be connected from other VM who have public ip. Now i can create a VM without public ip but then it does not have a internet access.
Now is there a way on Azure like on AWS where i can provision a NAT gateway or NAT instance on public subnet and let the private instances have internet connection
I also tried using NAT Gateway on Azure but it doesn't work unless i assign public ip to VM which is not what i want
I have two subnets lets say public_subnet & private_subnet , now i can ssh to my private vm from a jump but the thing is when i login to my private vm i cant install any package or even not able to ping or curl to any website. Both subnets were created using terraform so the configuration of subnets are all same there is no change is subnet configuration
Azure VMs have internet access by default, you dont have to do anything for them to have outbound access. It just works. Even without the public IP
There's two possibilities:
First one, under the same Vnet, you provision you VM without a public ip adress and then access it using Azure Bastion. You can find more details here.
Second one, is to provision two or more VMs in the same subnet one with public IP and the other without a public IP. and then access the one with private IP from the one with public IP.
We have a client that does not support NAT or RFC1918 addressing within VPN tunnels (encryption domain) and/or Peers.
The Azure virtual network gateways setup without a load balancer appear to not do NAT unless you have a load balancer out front which is good, correct me if I am wrong.
But can internal virtual machines in the virtual network at Azure have public ips only? Or does Azure require private virtual network addressing but you can also associate the public IP? We have set it up with the gateway public ip, virtual network with a 10.x.x.x subnet and associated public IPs to the sources or virtual machines.
Can virtual network machines only have a public IP at Azure? Or can you reach instances by public IP when connected to the Azure virtual network public IP even with private addressing in addition to the public IP binding?

Every Azure VM create by a private IP address, then we can associate a public IP address to it.

virtual network public IP even with private addressing in addition to
the public IP binding?
Yes, we can connect that VM with public IP address directly.
I've recently setup a point to site VPN on Azure. In doing so I have created:
Azure Virtual Network
Azure Virtual Network Gateway
Azure Virtual Network Gateway IP (static)
Azure VM
I was under the impression that any VM set to use the above said Virtual Network would all share the same public IP? However it appears that the Azure VM i setup is instead using its own dynamic public IP.
Is there a way to route any VM on the Custom Virtual Network I created through one public IP? IF so - how can I do this?
According to your description, you have create a point-to-side VPN. in this scenario, we can remove the public IP addresses from VMs, then you can access your VMs with private IP addresses via VPN.
You are correct - I have the VPN working correctly. My only concern is this, it'd be great that if any of those VM's in that private network shared the same static IP - that way I could grant access to that IP in my firewall to other systems i have in other hosting platforms (as they are all typically locked down by ip).
It sounds like your reference to availablity sets may be the phrase i was looking for to further google.. i will check it out and let me know
please let me know if anything I added above changes your answer/recommendations :)

You are talking about Azure ASM module (classic). In ASM module, VMs can use the same public IP address(NAT).
However it appears that the Azure VM i setup is instead using its own
dynamic public IP.
In Azure resource module, we can create Azure VMs with different Public IP addresses.

If you want to access those VMs from Internet and use one public IP address, we can create VMs in the same availability set, and deploy a Internet facing load balancer, then add NAT rules to them, in this way, we can access those VMs use the same public IP address and different ports.
I have multiple VMs in a vnet. Vnet has a static ip attached to it's interface. The network interfaces attached to individual VMs do not have any public ip associated. My expectation is that all outgoing traffic would get routed through the vnet ip, but it isn't the case. Each VM has a different public going IP. I have tried using curl ipinfo.io to test.
I need to ensure that all of the internet traffic from any VM in the vnet would get routed through a static ip address.
All outgoing traffic from the vnet should go through the same IP. I
want to whitelist this ip in my external services.
If your VMs deploy in ASM module, all the VMs in the same cloud service use the same public IP.
If your VMs deploy in ARM module, and want all VMs in the Vnet outgoing traffic through the same public IP address, we can use internet load balancer.
Also we can deploy S2S VPN between them, so we can add the public IP address to whitelist.
