Client: Confidential (Upwork Client – Hosting Platform on AWS)
Industry: SaaS Hosting / Cloud Infrastructure
The Challenge
A client running a cloud hosting platform on AWS was facing a persistent VPN connectivity issue. Their architecture relied on a Site-to-Site VPN via AWS Transit Gateway, and one of their key customer tunnels was dropping every hour for several minutes.
This recurring downtime posed a serious threat to platform availability, customer integrations, and overall satisfaction. With limited visibility into the root cause and unsuccessful internal troubleshooting, they turned to us for urgent help.
Our Solution
InfraxDev was brought into the project through Upwork to rapidly identify and resolve the issue. Here’s how we approached it:
- Audited VPN tunnel configurations, including customer gateway and AWS side
- Verified Dead Peer Detection (DPD) behavior and Phase 1/2 IPSec rekey settings
- Analyzed CloudWatch metrics and VPN logs for patterns
- Cross-checked timing alignment for rekey and DPD timers
🔍 Key Finding: A misalignment between the DPD timeout and rekey intervals on the customer’s equipment was causing the periodic drops.
We documented the misconfiguration clearly, guided the client through the update, and confirmed the successful implementation.
