Azure Firewall has no capacity to maintain source IP on outbound traffic?
Hello all, My use case: To have multiple static public IP addresses attached to Azure Firewall with SNAT rules configured so that the public IP isn't just randomly selected. We have multiple services that have whitelisting configured for specific public load balancer IPs and now we are trying to move them behind Azure Firewall. Since there is whitelisting on the destination, the public IP being randomly selected won't work. My resources: One instance of premium SKU Azure Firewall. Hub and spoke architecture. Route tables being used to force traffic through Firewall (routed to private IP of firewall) The research I have conducted: I have tried absolutely everything I can think of before coming to this forum and from what I can tell the 4 ways of outbound connectivity provided by Azure are: Default outbound connectivity. Against best practice to do this and won't work since its routing through a virtual appliance (firewall) Associate a NAT gateway to a subnet. This won't work since we have only one instance of Azure Firewall and the requirement for multiple public IPs to be used. Assign a public IP to a virtual machine. Not applicable, sitting in backend pool of a load balancer, single public IP to be used for multiple member servers. Using the frontend IP address(es) of a load balancer for outbound via outbound rules. Needs to go through the firewall, impossible unless we can somehow integrate the firewall between the load balancer and the backend pool? Expanding more on the load balancer scenario, I ran across this documentation in Microsoft Learn. This looks great to tackle the asymmetric routing issue, however, we are only interested in maintaining the source IP for outbound traffic, this would again just use the firewalls public IP for outbound traffic and again randomly select it. Consensus: It seems bizarre to me that Azure has no capacity for static SNAT configuration like most firewalls do. I would have thought a large amount of use cases would require this function. Am I missing something? Is there another workaround? Or is Azure just behind the 8ball with networking. Thanks heaps in advance for any help :) Much Appreciated, usernameone101Product Manager question - Azure Firewall
I would like to know if Azure Firewall team has plans to integrate geoblocking based on country codes into Azure Firewall policies? Today, we have to enlist a third party country code list and rebuild IPGroups into our AzFw policies daily. Other products such as WAF and Conditional Access allow for selecting a country code instead of IPv4 addresses.Az-firewall-mon(itor) - near real time Azure Firewall flow log analyser
Hello, networking expert! I’m excited to share with you an update on my personal open source project: az-Firewall-mon: Az-firewall-monitor is an open-source tool that helps you answer to the following question: what is happening in my azure Firewall right now? It provides an alternative and opinionable way to access and inspect Azure Firewall logs, without using Log Analytics or Kusto queries. It provides a simple and intuitive interface that shows you what is happening on your firewall right now (or almost). to filter your data you can use both a full text search or natural language thanks to his integration with chatGPT4. Here a sample full text search interaction: here a sample natural language interaction Try out az-firewall-monitor at https://az-firewall-mon.duckiesfarm.com or have a look at the source code on GitHub at https://github.com/nicolgit/azure-firewall-mon Thank you!Azure Firewall behind public load balancer configuration
Hi, I have a requirement to replace Sophos firewall with Azure Firewall Premium. The existing Sophos firewall is behind a public Azure load balancer (backend pool comprises the Sophos Firewall IPs). To set up a parallel configuration for Azure Firewall, I have configured a new public IP on the load balancer's frontend IP configuration. However, I do not see the Azure Firewall's public IP when trying to configure a backend pool. All the listed IPs belong to the same subnet as the load balancer's internal IP. As per the below article, one can configure firewalls behind an external load balancer. https://learn.microsoft.com/en-us/azure/architecture/example-scenario/firewalls/ I am trying to understand how to chain the public load balancer and Azure firewall such that I can access internal resources as is currently being done with the same public load balancer and Sophos firewall (NIC of Sophos is in the same subnet as internal NIC of this load balancer). Can someone please guide me? Thanks James
Internal API : Virtual Network support for Power Platform
Hello Everyone, We are using Custom Connectors from Power Automate Flows to initiate a call to the Internal API that is hosted in Azure through the MuleSoft Data Gateway. Since we are unable to activate the private endpoint for this internal API, we are seeking guidance on how to securely connect to the API via V-Net integration. Please advise. As per the Microsoft Documentation : Use custom connectors (preview) to securely connect to your services that are protected by private endpoints in Azure or services that are hosted within your private network. https://learn.microsoft.com/en-us/power-platform/admin/vnet-support-overview Thanks, -Sri
Issue with Azure VM Conditional Access for Office 365 and Dynamic Public IP Detection
Hi all, I have a VM in Azure where I need to allow an account with MFA to bypass the requirement on this specific server when using Office 365. I've tried to achieve this using Conditional Access by excluding locations, specifically the IP range of my Azure environment. Although I’ve disconnected any public IPs from this server, the Conditional Access policy still isn’t working as intended. The issue seems to be that it continues to detect a public IP, which changes frequently, making it impossible to exclude. What am I doing wrong?Public IPs on Azure
Hi, I have been trying to read documentation, but most likely I have used wrong search terms. But does anybody knows if the following kind of setup is possible on Azure? The main idea behind this question is, if I have servers and willing to have centralized FW control for the traffic coming in or out to/from these VMs, is this an option? Or if I assign the public IP to the VM, that can go out directly and skipping the centralized FW? All documents what I have see are speak about assigning the Public IP to the VMs, or having NATing, but with that we hit to the problem when port ranges extends widely.Azure SD-WAN
Hi, I'm looking for good SD-WAN options for connecting our branches to our Azure vWAN with secured hubs (Azure Firewall). The plan is to ditch our current on-prem network circuit + express route and move to Azure vWan as the central hub with branch offices connecting over SD-WAN. I've had a look at Azure Virtual WAN partners, regions, and available locations | Microsoft Learn. We currently do have Fortigate NGFW on-prem but doesn't belong to us as its managed by a vendor. Besides, deploying dual role Fortigate NGFW into the vWan hub seems like an over-kill since we already have Azure Firewall Premium? Would be grateful for your experience \ suggestions. Thanks
WordPress App how to restrict access to specific pages on the site
Hello all, I have a WordPress App hosted on Azure and I am struggling with how I can secure specific pages from public access. For example: www.mysite.com/wp-admin www.mysite.com/info.php I'd like it so that only specific IP addresses or Microsoft user accounts can access some, such as admin pages and for some pages I'd like no access at all, to where it just blocks any sort of visit. I've viewed the documentation for Front Door and some networking restrictions but that seems to be just IP addresses and I'm confused about how I can set those rule for specific pages within the App. I know WordPress offer plugins which have this sort of functionality but I'd like to take advantage of Azure's security features rather than plugins from WordPress. Any help is very appreciated. Thank you
Azure Firewall Traffic Cost
Hello, I'm calculating the azure firewall cost, but does the data processing cost mean the inbound/outbound traffic cost of azure firewall? Or mean the cost of data that azure fireall handles? And do I have to include the bandwidth price separately when calculating the price of azure firewall inbound/outbound traffic cost? Please reply. Thank you.
