Hairpin NAT support
Hairpin NAT — also known as NAT loopback and Hairpinning — is an advanced network feature that allows you to access port forwarded devices from inside the network using an external IP address — is now automatically enabled for all networks running eeroOS version 3.3 or later. You can check your network version by following these steps.
In order to use this feature, you will need to have configured a port forward on your network and ensure that the port needed to reach the network isn't blocked by another device (such as an upstream router)
