Configuring a Static IP Address on a Buffalo TeraStation

Before you begin this procedure you must decide on the IP address that will be assigned to the TeraStation. Make certain that you assign an address that is outside the range being assigned by any DHCP server (such as a wireless router). If you are uncertain about what address range is being used by your wireless router please refer to the owner's manual for the router.


  1. Access Settings, the TeraStation's web user interface, by entering the current IP address of the unit into a web browser. If the current IP is unknown the unit can be located using NAS Navigator. If NAS Navigator is not installed, download and install the application by clicking on the provided URLs here: Windows or Mac.
  2. Log in to Settings. The default username and password are "admin" and "password".
  3. From Settings, click on the "Network" tab on the left and then click on the widget icon to the right of "IP Address".
  4. Click on "LAN Port 1" to open the IP address settings for that port.
  5. This will display the current configuration. The default setting is for DHCP to be enabled so that the TeraStation gets an IP address automatically from a DHCP server. Click Edit to change the settings for LAN Port 1.
  6. From this dialog box you can make several changes. To set a static IP address click the radio button to disable DHCP and then type in the IP address and subnet mask. You can also set the frame size, enable or disable Wake on LAN, and set a default gateway and DNS servers. Note that only port 1 will allow you to set a default gateway. That gateway will be used by both ports if both ports are connected. Once you have the settings configured correctly click OK.

    Note: If you change the IP address you are using to access the interface you may be required to restart your browser and go to the new IP address to access the interface. If you are on a network with a DHCP server be certain to set the static IP on the TeraStation outside the range of addresses used by the DHCP server or you could get a potential IP address conflict!

  7. Click on "LAN Port 2" to configure the settings for that port.
  8. Note that the settings for port 2 are slightly different from port 1. From this dialog box you can disable port 2 entirely. Port 1 cannot be disabled. Also note, as mentioned in step 5, you cannot set a default gateway for port 2. It will use the same default gateway as port 1 if one is assigned. Once you have the settings configured correctly click OK.
