Hi, we’ve handled similar Sophos XG/XGS HA setups on Azure at SolutionzHere, including tricky Active-Active sync issues with LB + routing. We’ll audit your POC, fix HA sync/failover, and validate VPN, S2S, WAF, and routing end-to-end. Rate: ₹2,500/hr (recommended vs current for senior Azure+Sophos expertise) Effort:10–15 hours (2–3 days turnaround) We’ve resolved HA instability cases before—this looks fixable. One key question: Are you using Azure Standard Load Balancer with HA ports enabled on both firewalls, and is session persistence configured?

@Web1devloper

As an experienced cloud specialist, I understand the complexities that can arise in implementing High Availability setups in Azure, and the significance of a successful POC before integrating it in production. My extensive background with Sophos Firewall paired with deep knowledge of Azure networking makes me uniquely qualified to address your current HA challenges and drive your project towards success. Having spent years working on HA (Active-Active) setups and working with elements like VPN, S2S, NAT, and WAF, I am well-equipped to handle the issues you've encountered and ensure proper synchronization and failover behavior for a seamlessly operating environment. Time is of essence for you, and rest assured, immediate response and resolution is how I work. Let's collaborate to review your current setup efficiently, troubleshoot the issues, validate the proper functioning of different components along with HA configuration, and stabilize it for you. Your project deserves meticulous attention to detail and it's what I'll bring to the table if given an opportunity.

Dear Hiring manager, I can help you stabilize and validate your Sophos Firewall HA (Active-Active) setup in Azure for the POC phase. With 11+ years in cloud and network architecture, including Azure networking and firewall deployments, I’ve handled similar HA and VPN scenarios. I understand your current setup (2 Sophos firewalls, ELB/ILB, VNet) and the issue with HA not establishing properly. I can quickly review and troubleshoot synchronization, session persistence, probe configuration, routing, and load balancer rules—common causes in Azure HA setups. Approach: Audit existing Azure and Sophos configuration Fix HA (Active-Active) sync and failover behavior Validate health probes, UDRs, SNAT/DNAT, and LB rules Ensure VPN & S2S work seamlessly with HA Verify WAF rules and backend routing stability Perform end-to-end testing and provide recommendations Outcome: Fully working HA (Active-Active) setup in POC Stable VPN, S2S, WAF, and routing Clear documentation for production rollout I’m available to start immediately and can work closely with your team to resolve this quickly. Best regards, Jagrati.
