For an enterprise that needs its locations to stay online, I designed and deployed the first MultiWAN, multi-firewall configuration on pfSense — redundant internet links and high-availability firewalls that keep each site connected, packaged as a repeatable template rolled out across store locations.
The Challenge
A single internet link or a single firewall is a single point of failure — one hiccup and a location drops offline. The build had to deliver redundant WAN connectivity and highly-available firewalls, with the right static IPs coordinated per site, and no guesswork each time a new location came online.
What I Delivered
MultiWAN Redundancy
Multiple internet uplinks with automatic failover, so one ISP outage never takes a site down.
Multi-Firewall HA
A high-availability pfSense firewall pair — if one node fails, the other carries traffic seamlessly.
ISP & IP Coordination
Coordinated with ISPs to secure the correct static IP assignments for each link.
Failover Validation
Validated real failover behavior so the redundancy holds when it is actually needed.

A Repeatable, Resilient Pattern
I built it as a repeatable pattern: dual WAN links, a synchronized high-availability pfSense firewall pair, and tested failover cutovers — then documented it as a template so every future store location deploys the same proven, resilient setup.
The Result
The first redundant MultiWAN, multi-firewall deployment for the enterprise — resilient internet and firewalls at the edge, validated failover, and a repeatable template now rolling out across store locations.
