The information in this page is updated in accordance with firmware version TRB1_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 TRB255 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.
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:
The Mobile protocol is used to set up an interface which can establish a mobile WAN connection.
Mobile: General Settings
|Mode||NAT | Bridge | Passthrough; default: NAT||Mobile connection operating mode.
|SIM||SIM1 | SIM2; default: SIM1||Selects which SIM slot will be used for this interface.|
|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:
|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.
Mobile: Mobile Data Limit
The Mobile Data Limit section provides you with the possibility to set data usage limits for your mobile network interfaces and data usage warnings via SMS message in order to protect yourself from unwanted data charges.
In order to view the Mobile Data Limit section, the interface protocol must be set to Mobile.
|Enable data connection limit||off | on; default: off||Turns mobile data limitations on or off.|
|Data limit* (MB)||integer; default: 1000||The amount of data that is allowed to be downloaded over the specified period of time. When the limit is reached, the device will no longer be able to establish a data connection until the period is over or the data limit is reset.|
|Period||Month | Week | Day; default: Day||Data limit period after which the data counter is reset on the specified Start day.|
|Start day | Start hour||day [1..31] | day [Monday..Sunday] | hour [1..24]; default: hour 0||Specifies when the period of counting data usage should begin. After the period is over, the limit is reset and the count begins over again.|
|Enable SMS warning||off | on; default: off||Turns SMS warning on or off. When turned on and configured, sends an SMS message to a specified number after the SIM card uses a specified amount of data.|
|Data limit* (MB)||integer; default: none||The received data limit before sending an SMS warning. After reaching using the the amount of data specified in this field, the router will send an SMS warning message to the specified phone number.|
|Phone number||phone number; default: none||Recipient's phone numbers.|
