QUESTION

Azure Application Gateway: Cannot connect to backend server in

Asked 2021-Oct-18 at 07:13

Due to a recent layoff I got bombarded to azure admin out of the blue. I am pretty new to this and haven't yet got the chance to follow an admin course.

Facing the following issue: We host a couple of websites on an Azure Windows Server VM running IIS. These are accessible through an application gateway with a public IP. I was asked to add two new listeners for a new part of the website. I created the appropriate targeting in the backend pool, created http and https settings and added the listeners and Rules. However, when browsing to the site, it throws a 502 error and when i check the backend health, it gives below error.

Cannot connect to backend server. Check whether any NSG/UDR/Firewall is blocking access to server. Check if application is running on correct port.

I opened up the appropriate inbound ports on the NSG of the AZ Web interface on the VM and also on the local firewall of the server hosting IIS. AFAIK there are no additional NSG rules on the application gateway.

What am i missing here? :s

...

Answered 2021-Oct-18 at 07:13

I have extensive experience working with Application Gateways and I can tell you that a 502 Bad Gateway means something is definitely wrong at the backend or misconfigured AGW settings - that's what the error says, so nothing surprising. From my experience here are different scenarios I've faced for this error:

Backend server can't be reached due to an NSG Rule controlling access from the AGW subnet to the backend subnet.
Backend server can be reached but the port is not opened at the server's firewall.
Backend server can be reached, port is opened but application is not listening on those ports or application is not even running.
AGW listeners were misconfigured.

Here's what you can try:

First validate whether the Application and VM are fine by trying to access the application from another VM in the same subnet.

Next, try to get a VM in a different subnet and try to access the application, to mimic the AGW trying to connect to the backend. This will help you validate whether your NSGs are properly configured.

Lastly, revisit all the AGW settings and look for any misconfiguration in the listeners or other settings. (Added this based on your comments).

Taking this approach to troubleshooting will quickly help you identify which layer is causing the issue. Also, it would be a good practice to start documenting all AGW errors you get along your journey and also the remediation steps etc. This will help you tremendously in the future - this is not the last time you'll face issues with your AGW!

QUESTION

Azure Express route forced-tunneling with NVA

Asked 2021-Sep-28 at 14:31

I want to set-up forced tunneling in Azure. All traffic destined to internet should be routed to on-prem and exit to internet from there.

As far as i understand i need to advertise default route via BGP in Azure so that it replaces internet default route and send everything to on-prem via Express route.
Then i make UDRs 0.0.0.0/0 next hop to NVA Cisco firewall on all subnets in Azure.

All traffic from Azure subnets will go to NVA and from there it will be routed to on-prem or to another vNET.

Question is what about the traffic coming from on-prem to Azure ? I want that traffic to also go through NVA cisco firewall. How could it be done as gateway subnet do not support 0.0.0.0/0 UDRs with Express route setup.

...

ANSWER

Answered 2021-Sep-28 at 14:31

Your initial understanding of the setup is correct. You will have to advertise a default route of 0.0.0.0/0 via BGP from your on-premises to Azure, so that all your Azure traffic is sent to your on-premises via the ExpressRoute. And in order to filter all that traffic by an NVA, you can add a UDR with 0.0.0.0/0 on all the subnets (except the NVA subnet) with next hop as your Cisco Firewall NVA.

This setup will take care of the routing from Azure to on-premises which will go as below: All subnets --> Cisco NVA --> ExpressRoute gateway --> On-premises.

Now coming back to your question on what about the return traffic, yes GatewaySubnet do not support 0.0.0.0/0 UDRs but it supports UDRs with other address prefixes.

Hence, you can add a UDR to the ExpressRoute GatewaySubnet with the address prefix of your Vnet range with next hop type Virtual Appliance and IP address of your Cisco NVA. This will make sure that any traffic that comes from your on-premises for your Azure Vnet range, when reaches your ExpressRoute gateway will be forwarded to the Cisco NVA.

For example : If your Vnet address range is 10.0.0.0/16 then you can add a UDR to your ExpressRoute GatewaySubnet as below: Address prefix : 10.0.0.0/16 --> Next hop = Virtual Appliance --> Next hop = IP address of Cisco NVA So the routing from On-premises to Azure will go as below: On-premises --> ExpressRoute gateway --> Cisco NVA --> All subnets.

I've never worked with JSON files before and I cannot find a way to get certain fields out of the file using Python. The file in question is the Azure Service Tags file which lists all the Azure services by region and lists out the IP addresses used.

Azure Network Security Group Vs Route Tables

Asked 2021-Mar-04 at 01:47

Networking newbie here. From the Documentation it feels like both NSG and Routing tables(UDR) are doing the same thing - capable of defining ACLs at multiple levels (Vnet, Subnet, VM)

https://docs.microsoft.com/en-us/azure/virtual-network/network-security-group-how-it-works https://docs.microsoft.com/en-us/azure/virtual-network/virtual-networks-udr-overview

So how are they different and when is each used?

thanks.

...

ANSWER

Answered 2021-Mar-04 at 01:47

Azure automatically creates a route table for each subnet within an Azure virtual network and adds system default routes to the table. The route table is like a networking map that tells the traffic from one place to another place via the next hop. This generates the "path" but does not filter traffic.

The Azure network security group is used to filter network traffic to and from Azure resources in an Azure virtual network. It contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources. If there is no route to one place from a subnet, you even do not need to configure the security rules because there is no path. So when you consider the NSG it should have a successful network route.

For example, usually, we can access Azure VM in Azure virtual network via SSH or RDP over the Internet but it has a less secure way to expose the port 22 or 3389. We can restrict access to your Azure VM via specifying the source IP address in the NSG. This setting allows traffic only from a specific IP address or range of IP addresses to connect to the VM. Read more details here. In this scenario, we need to ensure that there is a route to the internet from your Azure virtual network and vice versa.

Static ip for azure app service using vnet integration

Asked 2020-Nov-24 at 07:39

I trying to assign a static ip-address ,or at least control the out bound traffic, for an azure app service with out having to invest in app service environment (it’s very expensive and not very flexible option). Reading up on "vnet integration"( https://docs.microsoft.com/en-us/azure/app-service/web-sites-integrate-with-vnet )

in the offical azure doc there exist options to force traffic to the vnet. From there it should be possible to route the all traffic using UDRs through NAT-gateway. Has any one here been able to make this work? I have read conflicting reports.

UPDATE Details of the scenario is as following. I want to communicate with a system behind an internet facing firewall that have rules based on internet routable ips. I want to leaverge app services and PaaS services in azure.

ANSWER

Answered 2020-Nov-24 at 07:39

This it not possible with azure NAT Gateway or any other native PaaS servie in azure. There are several open feedback items related to this issue (fixed outbound ip and Nat gateway with function app

I have created a ticket ticket in the microsoft documention hoping that they will clarify this in their offical doc on vnet integration.

One solution would be to leverage IaaS and install a custom reverse proxy on VM or container such as nginx. This is not a option in my scenario due to the maintenance this wil requiere over time.

UPDATE

This is now supported https://azure.github.io/AppService/2020/11/15/web-app-nat-gateway.html. Microsoft announced support last week! I have tested the solution and it works great.
