Improved access to cameras, home automation, and network storage with Hairpin NAT

We’re excited to announce that eero now supports Hairpin NAT for all networks running eeroOS version 3.3 or later. This feature has been one of the most requested to date and was built in close collaboration with our beta community (thank you!).

With Hairpin NAT (also known as NAT Loopback or Egress Hairpinning), eero checks outbound connections and reroutes them to a device on the local network if needed. This is especially useful when you have a device — like a local server — you’d like to access both at home and remotely. Without Hairpin NAT, two IP addresses would be needed to access the device — one for local connections and one for remote connections.

Developing Hairpin NAT presented some challenges — we had to ensure that it not only met our high bar for security, but also satisfied our performance and usability standards. The result is a Hairpin NAT implementation that’s true to eero’s core values — simple to to use, incredibly reliable, and secure.  

To get started with Hairpin NAT, just set up a port forward in the app for a device, and you’ll be able to access it locally and remotely. No custom firewall rules or tricky configurations needed. For more information on how to update your network, check out our Help Center.

As we continue to expand eero’s feature offering, we invite you to share your thoughts, ideas, and feedback in our eero community.
