Dear Hiring Manager, We have strong hands-on experience with both Microsoft Azure networking and Sophos Firewall (XG/XGS), including High Availability setups and complex cloud-based routing scenarios. Your POC requirement for an Active-Active HA configuration aligns closely with the kind of troubleshooting and implementation work we regularly handle. How we will approach your POC: • Review your existing Azure setup (VNet, subnets, NSGs, UDRs, Load Balancers) • Validate Sophos HA configuration (heartbeat, sync, interface bindings) • Troubleshoot Active-Active behavior with Azure Load Balancer (health probes, HA ports, floating IP) • Ensure session persistence and symmetric routing for proper failover • Validate VPN and Site-to-Site connectivity under HA conditions • Review and test WAF rules and backend routing through both nodes • Perform failover testing to confirm stability and synchronization We understand this is a POC phase with zero impact on production, and we can jump in immediately to stabilize the environment and help you move confidently toward production rollout. We’ve handled similar Azure + firewall HA scenarios and can quickly identify misconfigurations that typically block Active-Active setups. Available to start ASAP. Best regards, Jagrati.

Hello, thanks for posting this project. I specialize in designing and validating cloud-based firewall architectures with hands-on experience in Sophos XG/XGS and Azure networking. I will review your POC in East US, troubleshoot the Active-Active HA configuration, and ensure seamless synchronization, failover, VPN, S2S, WAF, and routing work end-to-end within the POC environment. My approach combines thorough configuration review, targeted troubleshooting, and validated testing to deliver a stable HA Active-Active setup in Azure before moving to production. What are the expected SLAs for VPN failover during the POC, and are there any preferred Azure regions beyond East US for staging? I am ready to start immediately and align with your tight timelines for the POC. Looking forward to hearing from you. Best regards,

I understand you have the infrastructure deployed (Internal/External LBs, VNets, and 2 Sophos Firewalls) but are struggling with the Active-Active HA synchronization. In Azure’s SDN environment, traditional HA heartbeat logic often fails due to how Azure handles IP forwarding and load balancer probes. My Approach to Fix Your POC: HA Sync Recovery: I will audit your NSGs and NIC settings (specifically IP Forwarding and MAC Address Spoofing) to ensure the Sophos nodes can establish a stable heartbeat link over the Azure fabric. Azure-Orchestrated Failover: I will prioritize Option B (Azure Fabric Probes) to ensure the External and Internal Load Balancers correctly identify "Healthy" nodes, preventing asymmetric routing issues. Traffic Symmetry: I will configure the Internal Load Balancer (ILB) and User-Defined Routes (UDR) to ensure that VPN, S2S, and WAF traffic flows remain symmetric even in an Active-Active state. Validation & Stability: Once the HA is established, I will perform a controlled failover test to ensure zero-downtime for your backend services before we discuss production replication.

Here’s a sharp, high-impact proposal under 1000 characters: Hi, Active-Active HA with Sophos on Azure often fails due to load balancer probes, session sync limits, or routing/NAT misalignment — not just firewall config. I can quickly identify and fix the root issue. What I’ll do: Audit your Azure setup (VNet, LB rules, probes, routing) Fix HA sync and ensure proper Active-Active behavior Validate failover, session persistence, and health checks Align VPN/S2S, WAF, and NAT with HA architecture Focus: Stable HA with correct traffic flow — not just “connected” firewalls. Experience: Worked on Sophos XG/XGS HA in cloud (Azure/AWS), including LB + routing issues. Timeline: Start immediately | Fix within hours (depending on config complexity) POC-first approach is correct — I’ll ensure it’s production-ready. Let’s stabilize your HA setup.

@filipb48

I personally experienced network security gateways such as Sophos UTM 9(ASG 9). I can help you quickly stabilize and validate your HA (Active-Active) setup for Sophos Firewall in Azure. I have hands-on experience with Sophos environments (including Sophos UTM 9 and XG/XGS) and strong expertise in Azure networking (VNet, Load Balancers, routing, and VPN architecture). I understand the common challenges with Active-Active HA in cloud environments—especially around synchronization, session persistence, asymmetric routing, and load balancer health probes. For your POC, I will: * Review your current Azure architecture (External/Internal LB, VNet, routing tables) * Diagnose why HA Active-Active is not forming properly * Fix synchronization and failover behavior between both firewalls * Ensure correct configuration of Azure Load Balancers (probe, SNAT, HA ports if required) * Validate VPN and Site-to-Site connectivity under HA * Verify WAF functionality and backend routing stability * Assist with structured testing to confirm resilience I’m comfortable working strictly in POC and documenting everything clearly so it can be replicated in production later. I can start immediately and focus on resolving the HA issue as the top priority. Let’s connect and get your setup working as intended. Best regards, Filip

Hello, I can help stabilize and complete your Azure-based Sophos Firewall HA (Active-Active) POC by identifying and resolving the root cause of the synchronization issue. With strong experience in Azure networking (VNet, UDRs, Load Balancers) and Sophos XG/XGS deployments, I will review your current architecture, validate HA prerequisites (interfaces, heartbeat, session sync, LB configuration), and fix the Active-Active setup to ensure proper failover and traffic distribution. I will also verify that VPN, Site-to-Site tunnels, WAF rules, and routing behave correctly under HA conditions. Once stabilized, I’ll assist with structured testing and document the setup so it can be replicated smoothly in production. Before give you time and cost estimation could you please give me the answers of my questions : Is session persistence configured on your Azure Load Balancers? Are both firewalls in the same availability zone or different zones? Have you configured HA heartbeat interfaces correctly? Thankss Divu..

@SidUSA

Hello!!! Quantum Code Solutions is ready to resolve the HA Active-Active synchronization issues in your Azure POC. The primary challenge in East US Sophos deployments often stems from Load Balancer probe configurations or incorrect NIC routing in the VNet. Recently, a similar HA setup was fixed for a logistics firm involving complex backend routing. The team corrected the internal load balancer rules and updated the Sophos XML configurations to allow seamless failover. This stopped data loss during sync and stabilized the S2S VPN and WAF rules. Eager to get connected with you. Best regards, Quantum Code Solutions
