The information in this page is updated in accordance with firmware version RUT36X_R_00.07.02.7.


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 RUT360 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 are two types of WAN interfaces on the device:

  • Ethernet WAN
  • Mobile WAN

Each supports different types of protocols and setups, which are described in the sections below.

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

The static address protocol uses a predefined manual configuration instead of obtaining parameters automatically via a DHCP lease.

Static: General Settings

Networking rutos manual wan wan configuration general setup static address.png

Field Value Description
IPv4 address ip4; default: none The IPv4 address interface of this interface. An IP address identifies a device on a network and allows it to communicate with other devices.
IPv4 netmask netmask; default: none The IPv4 netmask of this interface. A netmask is used to define how "large" a network is by specifying which part of the IP address denotes the network and which part denotes a device.
IPv4 gateway ip4; default: none The IPv4 address gateway of this interface. An interface's gateway is the default next hop address to access other networks.
DNS servers ip4; default: none DNS server addresses that this interface will use. If left empty, DNS servers are assigned automatically. To see what DNS servers are currently used, you can check the contents of the /tmp/ file.

Static: DHCP Server

A DHCP (Dynamic Host Configuration Protocol) server is a service that can automatically configure the TCP/IP settings of any device that requests such a service. If you connect a device that has been configured to obtain an IP address automatically, the DHCP server will lease out an IP address from the available IP pool and the device will be able to communicate within the private network.

This section is used to set up the main operating parameters of the DHCP server.

Networking rutos manual wan wan configuration static dhcp server.png

Field Value Description
Enable DHCP Enable | Disable | DHCP Relay*; default: Enable Turns the DHCP server on or off or enables DHCP relay*.
If DHCP Relay* is selected, you will be prompted to enter an IP address of another DHCP server in your LAN. In this case, whenever a new machine connects to this device, it will redirect any DHCP requests to the specified DHCP Server.
Start integer [1..255]; default: 100 The starting IP address value. e.g., if your device’s LAN IP is and your subnet mask is that means that in your network a valid IP address has to be in the range of [] ( is a special unavailable address). If the Start value is set to 100 then the DHCP server will only lease out addresses starting from
Limit integer [1..255]; default: 150 How many addresses the DHCP server can lease out. Continuing from the example above: if the start address is and the server can lease out 150 addresses, available addresses will be from to (100 + 150 – 1 = 249; this is because the first address is inclusive).
Lease time integer [1..999999]; default: none
integer [2..999999]*
integer [120..999999]**
A DHCP lease will expire after the amount of time specified in this field and the device that was using the lease will have to request a new one. However, if the device stays connected, its lease will be renewed after half of the specified amount of time passes (e.g., if lease time is 12 hours, then every 6 hours the device will ask the DHCP server to renew its lease).
The minimal amount of time that can be specified is 2 minutes.
*If selected Units is Minutes.
**If selected Units is seconds.
Units Hours | Minutes | Seconds; default: Hours Lease time units.

* When an interface is set to act as a DHCP Relay, it redirects all received DHCP request messages to another specified DHCP server:

The DHCP client protocol is used to set up an interface which obtains its configuration parameters automatically via a DHCP lease.

Field Value Description
Hostname to send when requesting DHCP string; default: none A hostname for this interface used to identify this machine on the DHCP server.


The Mobile protocol is used to set up an interface which can establish a mobile WAN connection.

Mobile: General Settings

Networking rutos manual wan mobile configuration general setup dualsim 0 dualmodem 0.png

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 RUT360 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 RUT360 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.

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.

Field Value Description
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.
Clear Collected Data - (interactive button) Clears the data limit counter.
