IP Conflict Resolver for VPN Tunnels

Problem Context

Network engineers and MSPs use IPsec VPNs to connect customers to shared firewalls in Azure or other cloud platforms. When two customers get the same public IP from their ISP, the VPN wizard and CLI fail to create tunnels, blocking new customer onboarding. This forces manual troubleshooting, which often doesn’t work, leading to lost revenue and wasted time.

Pain Points

The VPN setup tools (Fortigate wizard/CLI) reject duplicate IPs with no workaround. Manual IP renumbering is complex and error-prone. Support channels provide no solution, leaving engineers stuck. Every conflict delays customer onboarding, directly impacting revenue and operational efficiency.

Impact

Each IP conflict can cost **$1,000–$10,000+ per customer*- in lost deals, downtime, and emergency fixes. Engineers waste 5+ hours per week trying failed workarounds. Without a fix, MSPs cannot scale their VPN services, limiting growth and damaging reputation with customers who experience repeated outages.

Urgency

This is a blocker for new business. Until resolved, MSPs cannot onboard customers with duplicate IPs, which is common with shared firewalls and ISPs. The problem won’t fix itself—it requires a dedicated tool to automate conflict resolution and prevent future issues.

Target Audience

This affects *MSPs, cloud architects, and network engineers- managing VPNs for B2B customers. It’s especially painful for companies using shared firewalls (Fortigate, Palo Alto, Cisco) in Azure/AWS, where IP conflicts are frequent. Smaller MSPs feel it most acutely but larger firms also struggle at scale.

Solution Approach

A *proxy service that automatically detects IP conflicts- and rewrites VPN configurations to avoid them. It hooks into Fortigate/Azure APIs to monitor IPs in real-time, then generates and deploys conflict-free tunnel settings (e.g., NAT, IP aliasing, or renumbering) without manual intervention. The tool runs as a background service, ensuring VPNs stay up even when IPs change.

Key Features

1. Auto-generated conflict-free configs: Uses proprietary algorithms to rewrite tunnel settings (e.g., adding NAT rules or IP aliases) to bypass conflicts.
2. One-click deployment: Pushes updated configs via API/CLI to Fortigate or Azure, restoring VPN connectivity in seconds.
3. Recurring conflict monitoring: Continuously checks for new IP issues, sending alerts before they cause outages.

User Experience

Engineers *set it up once- via a web dashboard, linking their Fortigate/Azure accounts. The tool runs silently in the background, blocking conflicts before they happen. When a conflict is detected, it *auto-fixes the config- and notifies the user. No CLI commands or manual edits needed—just working VPNs. For MSPs, it reduces onboarding delays from hours to seconds and eliminates emergency troubleshooting.

Differentiation

No existing tool—not Fortigate, not Azure, not third-party VPN managers—solves this. Competitors either *ignore the problem- or require manual, error-prone workarounds. This tool is the *only dedicated IP conflict resolver- for VPN tunnels, with *native integrations- and automated fixes. It’s also self-service: no IT approval or complex setup required.

Scalability

Starts with *small MSPs (5–50 VPNs)- and scales to enterprise MSPs (1,000+ VPNs). Pricing tiers grow with usage (e.g., $49/mo for 50 VPNs, $99/mo for 200+). Add-ons like *multi-cloud support (AWS/GCP) or priority alerts- increase revenue per user. The API-first design allows future integrations (e.g., ConnectWise, Datto) to expand the market.

Expected Impact

MSPs *recover lost revenue- from blocked onboarding and *save 10+ hours/week- on manual troubleshooting. VPN uptime improves, reducing customer churn. The tool *future-proofs VPN management- by handling IP conflicts automatically, even as the MSP’s customer base grows. For engineers, it *eliminates a major frustration point- and lets them focus on higher-value work.
