Networking out Private VNET in AZURE with a third party app such as payment gateway?
I need to do networking so that my VNET in Azure connects to third party applications such as payment gateways or messaging apps which are in Public internet. Please let me know the options and why we should prefer one over the other?
Spoke-Hub-Hub Traffic with VPN Gateway BGP and Firewall Issue
Hello, I’m facing a situation where I’m trying to have Azure Firewall Inspection on the VPN Gateway VNET-VNET Connectivity. It seems to work if I go from SpokeA-HubAFirewall-HubAVPN—HubBVPN-SpokeB but if I try to go from SpokeA-HubAFirewall-HubAVPN-HubBVM or Inbound Resolver it fails to route correctly according to Connectivity Troubleshooter it stops at HubAVPN with Local Error: RouteMissing but then reaches destination health so makes me believe it’s getting there but not following the route I want it to take which might be causing routing issues. What Am I missing here? This connectivity was working before introducing the Azure Firewall for Inspection with the UDR. Is what I’m trying to accomplish not possible? I’ve tried different types of UDR rules on the Gateway Subnet, and this is my most recent configuration. The reason I’m trying to accomplish this is because I’m seeing a similar error in our Hub-Spoke Hybrid environment and I’m trying to replicate the issue. Current Configuration 2x Hubs with Spoke networks attached so example Hub-Spoke-A Configuration: Hub-A Contains following subnets and Resources VPN Gateway - GateWaySubnet Azure Firewall - AzureFirewallSubnet Inbound Private Resolver - PrivateResolverSubnet Virtual Machine – VM Subnet Gateway Subnet has an attached UDR with the following routes Propagation - True Prefix Destination – Hub-B Next Hop Type – Virtual Appliance Next Hope IP – Hub-A Firewall Prefix Destination – Spoke-B Next Hop Type – Virtual Appliance Next Hope IP – Hub-A Firewall Hub-Spoke-B Configuration: Hub-B Contains following subnets and Resources VPN Gateway - GateWaySubnet Azure Firewall - AzureFirewallSubnet Inbound Private Resolver - PrivateResolverSubnet Virtual Machine – VM Subnet Gateway Subnet has an attached UDR with the following Routes Propagation - True Prefix Destination – Hub-A Next Hop Type – Virtual Appliance Next Hope IP – Hub-B Firewall Prefix Destination – Spoke-A Next Hop Type – Virtual Appliance Next Hope IP – Hub-B Firewall Spoke Subnets has an attached UDR with the following Routes Propagation - True Prefix Destination – 0.0.0.0/0 Next Hop Type – Virtual Appliance Next Hope IP – HubA/HubB Firewall (Depending on what hub its peered to) VPN Gateways HA VNET-VNET with BGP Enabled. I can see that it knows the routes and like I said this was working prior introducing the UDRs for force traffic through the azure firewall.
Can only remote into azure vm from DC
Hi all, I have set up a site to site connection from on prem to azure and I can remote in via the main dc on prem but not any other server or ping from any other server to the azure. Why can I only remote into the azure VM from the server that has Routing and remote access? Any ideas on how I can fix this?
Route-metrics in Azure P2S VPN
We have the following setup in our environment: Azure VPN Gateway S2S-VPN between gateway and our on-premise datacentre. P2S-VPN between gateway and clients. This P2S VPN is configured with AAD-authentication and the VPN profile is assigned to a client via Intune and XML-configuration. I have attached a stripped down version of our .xml with information that is not sensitive. (azurevpn.xml). It's in the zipped file. This setup is working overall fine, we add some routes to direct the traffic to the right place. We also have a management-VPN deployed that some of our employees use to get access to our network equipment and other administrative devices. This is a Cisco Anyconnect VPN. When connected to both this VPN-profile and the AzureVPN it let's them traverse both the management-net and the "customer"-net and let's them query DNS in both nets. The Anyconnect-VPN just as the AzureVPN has routes assigned to it, which when connected, one of the routes gets assigned a metric of 35. When then the P2S-VPN is connected it assigns the metric 311 on the same route. 311 seems to be the "default" metric on the routes specified in our .xml. This causes the issues in our case and we need to assign a metric lower then 35 to the P2S-route. Is there any way to assign a metric to a route that we push with the .xml? According to the Microsoft Docs here https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-profile-intune which links to this Docs https://docs.microsoft.com/en-us/windows/client-management/mdm/vpnv2-csp says you are able to do this. However if we try to add for example "<metric>25</metric> to the xml this gets ignored on the client. I have attached a section of the AzureVpnCxn.log which is stripped of sensitive information where this can be seen. Please advicePlease clarify for required certificates for P2S connection in Azure
Hi, For Point-to-Site connection in Azure, certificates of Windows are exported. Depending on Windows system, I have seen different situation in certmgr.msc as below 1st Windows system 2nd Windows system 3rd Windows system Please let me know Which certificates we need to export at certmgr.msc? If we need to export Personal certificate, what I need to do, if no certificates are showing or another certificates (like Adobe) are showing at Personal? Please clarify with additional required information. We’ll be thankful for your assistance. With Regards NndnG
BGP Routing from and to VPN Gateway
Hello All, I am setting up a lab concerning vWAN connection to onprem via SDWAN and I have some issues getting the routing to work properly. I have a hub which symbolizes the on-premises hub with a VPN gateway (gw-onprem) and a VM (on-prem-hubvm) deployed. Attached to the onprem-hub is a) on-prem spoke with a VM (on-prem VM). b) two vnets that symbolize the sdwan. Both of which have a VPN gateway as well as one VM each deployed (gw-sd-1/2) The SDWan Gateways are connected via s2s to two different vWAN hubs in two different locations. The vWAN has a third Hub which is not directly connected to on-prem What I am trying to lab is what direction the traffic is tacking from the vWAN Hubs to the last on-premise VM. The traffic currently goes all the way through the s2s vpn connection, but it gets dropped afterwards. I am struggling to set-up the routing from the sd-gw's to the on-premises machine. The routing needs to work through BGP The goal of the Lab is to see which path to on-premises is preferred if the hub preference is AS Path (shortest BGP Path). BGP is enabled on all VPN Gateways The SD GWs are peered to the onprem Hub GW but no vnet peering. The on-premises Vnets are peered. Somehow the VPN Gateways are not learning the routes to on-premises. I tried pointing the way with UDRs but somehow it also isnt working I've tried setting up UDRs so that the traffic would be the following vWAN Hub -> sd GW > sd VM > GW-onprem (> on-prem-hubvm) > on-prem VMInternal 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, -SriDeploy Dynamic Routing (BGP) between Azure VPN and Third-Party Firewall (Palo Alto)
Overview This blog explains how to deploy dynamic routing (BGP) between Azure VPN and a third-party firewall. You can refer to this topology and deployment guide in scenarios where you need VPN connectivity between an on-premises third-party VPN device and Azure VPN, or any cloud environment. What is BGP? Border Gateway Protocol (BGP) is a standardized exterior gateway protocol used to exchange routing information across the internet and between different autonomous systems (AS). It is the protocol that makes the internet work by enabling data routing between different networks. Here are some key points about BGP: Routing Between Autonomous Systems: BGP is used for routing between large networks that are under different administrative control, known as autonomous systems (AS). Each AS is assigned a unique number. Path Vector Protocol: BGP is a path vector protocol, meaning it maintains the path information that gets updated dynamically as routes are added or removed. This helps in making routing decisions based on path attributes. Scalability: BGP is designed to handle a large number of routes, making it highly scalable for use on the internet. Policy-Based Routing: BGP allows network administrators to set policies that can influence routing decisions. For example, administrators can prefer certain routes over others based on specific criteria such as path length or AS path. Peering: BGP peers are routers that establish a connection to exchange routing information. Peering can be either internal (within the same AS) or external (between different AS). Route Advertisement: BGP advertises routes along with various attributes such as AS path, next hop, and network prefix. This helps in making informed decisions on the best route to take. Convergence: BGP can take some time to converge, meaning to stabilize its routing tables after a network change. However, it is designed to be very stable once converged. Use in Azure: In Azure, BGP is used to facilitate dynamic routing in scenarios like connecting Azure VNets to on-premises networks via VPN gateways. This dynamic routing allows for more resilient and flexible network designs. Switching from static routing to BGP for your Azure VPN gateway will enable dynamic routing, allowing the Azure network and your on-premises network to exchange routing information automatically, leading to potentially better failover and redundancy. Why BGP? BGP is the standard routing protocol commonly used in the Internet to exchange routing and reachability information between two or more networks. When used in the context of Azure Virtual Networks, BGP enables the Azure VPN gateways and your on-premises VPN devices, called BGP peers or neighbors, to exchange "routes" that will inform both gateways on the availability and reachability for those prefixes to go through the gateways or routers involved. BGP can also enable transit routing among multiple networks by propagating routes a BGP gateway learns from one BGP peer to all other BGP peers. Diagram Pre-Requisite Firewall Network: Firewall with three interfaces (Public, Private, Management). Here, the LAB has configured with VM-series Palo Alto firewall. Azure VPN Network: Test VM, Gateway Subnet Test Network Connected to Firewall Network: Azure VM with UDR pointing to Firewall's Internal Interface. The test network should be peered with firewall network. Configuration Part 1: Configure Azure VPN with BGP enabled Create Virtual Network Gateway from marketplace Provide Name, Gateway type (VPN), VPN SKU, VNet (with dedicated Gateway Subnet), Public IP Enable BGP and provide AS number Create Note: Azure will auto provision a local BGP peer with an IP address from Gateway Subnet. After deployment the configuration will look similar to below. Make a note of Public IP and BGP Peer IP generated, we need this while configuring VPN at remote end. Create Local Network Gateway Local Network Gateway represents the firewall VPN network Configuration where you should provide remote configuration parameters. Provide Name, Remote peer Public IP In the Address space specify remote BGP peer IP (/32) (Router ID in case of Palo Alto). Please note that if you are configuring static route instead of dynamic you should advertise entire remote network ranges which you want to communicate through VPN. Here BGP making this process much simpler. In Advanced tab enable BGP and provide remote ASN Number and BGP peer IP create Create Connections with default crypto profile Once the VPN Gateway and Local Network Gateway has provisioned you can build connection which represents IPsec and IKE configurations. Go to VPN GW and under Settings, Add Connection Provide Name, VPN Gateway, Local Network Gateway, Pre-Shared Key Enable BGP If Required, Modify IPsec and IKE Crypto setting, else leave it as default Create Completed the Azure end configuration, now we can move to firewall side. Part 2: Configure Palo Alto Firewall VPN with BGP enabled Create IKE Gateway with default IKE Crypto profile Provide IKE Version, Local VPN Interface, Peer IP, Pre-shared key Create IPSec Tunnel with default IPsec Crypto profile Create Tunnel Interface Create IPsec Tunnel: Provide tunnel Interface, IPsec Crypto profile, IKE Gateway Since we are configuring route-based VPN, tunnel interface is very necessary to route traffic which needed to be encrypted. By this configuration your tunnel should be UP Now finish the remaining BGP Configurations Configure a Loopback interface to represent BGP virtual router, we have provided 10.0.17.5 IP for the interface, which is a free IP from public subnet. Configure virtual router Redistribution Profile Configure Redistribution Profile as below, this configuration ensures what kind of routers needed to be redistributed to BGP peer routers Enable BGP and configure local BGP and peer BGP parameters Provide Router ID, AS number Make sure to enable Install Route Option Configure EBGP Peer Group and Peer with Local BGP Peer IP, Remote (Azure)BGP Peer IP and Remote (Azure) BGP ASN Number. Also Specify Redistribution profile, make sure to enable Allow Redistribute Default Route, if you need to propagate default route to BGP peer router Create Static route for Azure BGP peer, 10.0.1.254/32 Commit changes Test Results Now we can test the connectivity, we have already configured necessary NAT and default route in Firewall. You can see the propagated route in both azure VPN gateway and Palo Alto firewall. FW NAT Name Src Zone Dst Zone Destination Interface Destination Address Service NAT Action nattovm1 any Untrust any untrust_inteface_pub_ip 3389 DNAT to VM1 IP nattovm2 any Untrust any untrust_interface_pub_ip 3000 DNAT to VM2 IP natto internet any Untrust ethernet1/1 default 0.0.0.0/0 SNAT to Eth1/1 Stattic Route configured: Azure VPN GW Connection Status and Propagated routes Azure Test VM1 (10.0.0.4) Effective routes Palo Alto BGP Summary Palo Alto BGP connection status Palo Alto BGP Received Route Palo Alto BGP Propagated Route Final Forwarding table Ping and trace result from Test VM1 to test VM2 Conclusion: BGP simplifies the route advertisement process. There are many more configuration options that we can try in BGP to achieve smooth functioning of routing. BGP also enables automatic redundancy and high availability. Hence, it is always recommended to configure BGP when it comes to production-grade complex networking.
