IKEv2 and Windows 10/11 drops connectivity but stays connected in Windows
I’ve seen this with 2 different customers using IKEv2 User VPNs (virtual wan) and Point to Site gateways in hub and spoke whereby using the VPN in a Always On configuration (device and user tunnel) that after a specific amount of time (56 minutes) the IKEv2 connection will drop the tunnel but stay connected in Windows. To restore the connection, you just reconnect. has anyone else had a similar experience? I’ve seen the issue with ExpressRoute and with/without Azure firewalls in the topology too.

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.

routing table
Hello, I have a virtual network with 192.168.0.0/24. In the virtual network is a firewall with 192.168.0.5. Now I want to route any outgoing traffic on the virtual network through the firewall. If I create a rule 0.0.0.0/0 to 192.168.0.5 - The internal devices can not reach each other. What is the best way to set the routing rules here? Greetings and thanks Stefan
Access to the delegated container subnet from the rest of the network
Hi All, We have an on-premise network: ONPREM-VLAN which is connected to an Azure VLAN: AZUREVLAN1 using Site to Site VPN connection. This AZUREVLAN1 is in subscription-1. We have another subscription: subscription-2 which has two more VLANs: AZUREVLAN2 and AZUREVLAN3. AZUREVLAN2 is one Azure region (same as AZUREVLAN1 i.e. Australia Southeast) and AZUREVLAN3 is in another Azure region (i.e. In Australia East). We have enabled Vnet peering between all the three VLANs. We have also established routing from our on-premise network: ONPREM-VLAN to all the three Azure VLANs. However, when we created a delegated container subnet in AZUREVLAN3 it is only accessible from other subnets within AZUREVLAN3. it is not accessible from any other VLANs (AZUREVLAN2, AZUREVLAN1 and ONPREM-VLAN) in the network. Here is the screenshot of that delegated container subnet: Is there a way i can enable routing from the rest of the network to this delegated subnet?
Azure Firewall query
Hi Community, Our customer has a security layer subscription which they want to route and control all other subscription traffic via. Basically, they want to remove direct VPeers between subscriptions and to configure Azure Firewalls to allow them to control and route all other subscriptions traffic. All internet traffic would then be routed down our S2S VPN to our Palo Alto’s in Greenwich for internet access (both ways). However, there may be some machines they would assign Azure Public IP’s to for inbound web server connectivity, but all other access from external clients would be routed via the Palos inbound. Questions: Which one (Azure Firewall or Azure WAN) would be best option? What are the pros and cons? Any reference would be of great help.
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?
