The information in this page is updated in accordance with firmware version TRB5_R_00.07.03.4.


The WAN page is used to to set up WAN network interfaces, which are used to connect device with external networks.

This manual page provides an overview of the WAN windows in TRB500 devices.


The WAN section displays WAN network interfaces currently existing on this device.

From here you can turn the interfaces on or off, change their priority* or enter an interface's configuration page.

* You can change the priority by dragging and dropping an interface to another position. Moving an interface changes its metric value in the configuration file. Interfaces that are higher on the list have greater priority.

Interface configuration

This section provides information on WAN interface configuration. There is one type of WAN interface on the device:

  • Mobile WAN

To begin configuring an interface, click the 'Edit' button on the right side of the interface:

Field Value Description
Mode NAT | Bridge | Passthrough; default: NAT Mobile connection operating mode.
  • NAT - the mobile connection uses NAT (network address translation).
  • Bridge - bridges the LTE data connection with LAN. The device assigns its WAN IP address to another device (first connected to LAN or specified with MAC address). Using Bridge mode will disable most of the device’s capabilities.
  • Passthrough - in this mode the TRB500 shares its WAN IP to a single LAN device (first connected to LAN or specified with MAC address). The LAN device will get WAN IP of TRB500 instead of LAN IP. Using Passthrough mode will disable most of the device’s capabilities.
Auto APN off | on; default: on The Auto APN feature scans an internal Android APN database and selects an APN based on the SIM card's operator and country. If the first automatically selected APN doesn't work, it attempts to use the next existing APN from the database.
APN / Custom APN string; default: none An Access Point Name (APN) is a gateway between a GSM, GPRS, 3G or 4G mobile network and another computer network. Depending on the contract, some operators may require you to use an APN just to complete the registration on a network. In other cases, APN is used to get special parameters from the operator (e.g., a public IP address) depending on the contract.
An APN Network Identifier cannot start with any of the following strings:
  • rac;
  • lac;
  • sgsn;
  • rnc;
it cannot end in:
  • .gprs;
and it cannot contain the asterisk symbol (*).
Bridge | Passthrough: MAC Address mac; default: none Specifies the MAC address of the device that will receive the mobile interface's IP address in Bridge or Passthrough mode.
Note: this field only becomes visible when using Bridge or Passthrough mode.
