Ethernet Gateway AutoIP Feature

An Ethernet Gateway running version gateway firmware or later includes a feature which allows a user to access the Local HTTP Configuration Page in order to configure the gateway without connecting the gateway to a DHCP enabled network. This feature is useful if you are operating your gateway on a network which requires a static IP address. It allows you to access the Local Configuration Page when the gateway is not connected to a network that supports DHCP, and thus apply a static IP configuration.

Enabling the self-assigned IP feature

To enable this, simply connect the gateway’s Ethernet port to a PC’s Ethernet port which is not configured with an IP address, and power on the gateway running firmware or later. If this is done, both the PC (which cannot already have an IP address assigned) and the gateway will have a self-assigned IP address within the same range, and the gateway’s HTTP Interface will be available and active for a matter of minutes. The Local HTTP Configuration page can be accessed through the PC’s browser, and the gateway can be configured with the desired configurations.

If the HTTP Interface is in Read-Access Only, you will need to:

  • Power the gateway off.
  • Press and hold the Utility button.
  • Power the gateway on.
  • Hold the Utility button for 5 seconds until all three LEDs show solid red simultaneously then immediately release.

    Note: do not hold the Utility button any longer or the gateway will reset.

The AutoIP self-assigned IP address of the gateway will be:

On the rare occasion that the PC attempts to assign itself this IP address, it should automatically adjust as to allow the gateway this self-assigned address.

LED’s and confirming the gateway is in AutoIP mode

With default configurations, the Ethernet Gateway 4 will attempt to retrieve an IP address via DHCP when it is powered up. After the gateway completes its start up self-test, it will attempt to retrieve an IP address via DHCP, and if it is unable to do so after 2 minutes, it will enter the AutoIP mode. This can be confirmed with the LED sequence as described below.

GF 1s, GF 1s, GF 1s - Power on

G, G, G with R LED display cycling from top to bottom for approximately 5 seconds - self test

G 1s, G 1s, G 1s - self test completed

2x RF 1s, Off, Off - gateway verifying Ethernet connection

GF 1s, Off, Off - gateway attempting to request IP address via DHCP for approximately 20 seconds

*rapid flashing R, rapid flashing R, rapid flashing R - gateway has entered AutoIP mode


After performing the steps above, you should be able to configure your gateway with a static IP (and other configurations) through the local HTTP Configuration page of the gateway. Feel free to contact with related inquiries.
