Template:Networking rutos manual wan
The information in this page is updated in accordance with firmware version .
Summary
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 {{{name}}} devices.
If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.
WAN
The WAN section displays WAN network interfaces currently existing on this device.
[[File:Networking_rutos_manual_wan_mobile_{{{mobile}}}_dualsim_{{{dualsim}}}_dualmodem_{{{dualmodem}}}_wired_{{{wired}}}_v3.png|border|class=tlt-border]]
From here you can turn the interfaces, enable/disable interface's failover, create interfaces, 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.
If you hover mouse over the question mark 
global IPv6 addresses and IPv6 prefix delegation will be displayed.
Interface configuration
This section provides information on network interface configuration. There are {{{no_of_if}}} main types of interfaces on the device:
Different types of interfaces can be configured under different protocols:
| Static | DHCP | DHCPv6 | PPPoE |
|---|
To begin configuring an interface, click the 'Edit' button on the right side of the interface:
General Setup
The General Setup section is used to configure the protocol of an interface and all the different parameters that go along with each protocol. If None protocol is chosen, all other interface settings will be ignored. The following sections are different for each protocol.
General Settings: Static
The static protocol uses a predefined manual configuration instead of obtaining parameters automatically via a DHCP lease.
| Field | Value | Description |
|---|---|---|
| Enable | on | off; default: on | Enable interface. |
| 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: 255.255.255.0 | 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 gateway address used by this interface. An interface's default gateway is the default address through which all outgoing traffic is directed. |
| IPv4 broadcast | ip4; default: none | The IPv4 broadcast address used by this interface. IP broadcasts are used by BOOTP and DHCP clients to find and send requests to their respective servers. |
| 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/resolv.conf.auto file. |
General Settings: DHCP
The DHCP protocol is used to set up an interface which obtains its configuration parameters automatically via a DHCP lease.
| Field | Value | Description |
|---|---|---|
| Enable | on | off; default: on | Enable interface. |
| Hostname to send when requesting DHCP | string; default: none | A hostname for this interface used to identify this machine on the DHCP server. |
General Settings: DHCPv6
The DHCPv6 protocol is used to set up an IPv6 interface which obtains its configuration parameters automatically via a DHCP lease.
| Field | Value | Description |
|---|---|---|
| Enable | on | off; default: on | Enable interface. |
General Settings: PPPoE
The PPPoE protocol is used to set up a PPP (Point-to-Point Protocol) connection over the Ethernet port.
| Field | Value | Description |
|---|---|---|
| Enable | on | off; default: on | Enable interface. |
| PAP/CHAP username | string; default: none | Username used in PAP/CHAP authentication. |
| PAP/CHAP password | string; default: none | Password used in PAP/CHAP authentication. |
| Access Concentrator | string; default: none | The Access Concentrator to connect to. ISPs used Access Concentrators to route their PPPoE connections. Usually, the settings are received automatically, however in some cases it is required to specify the name for an Access Concentrator. Leave empty to detect Access Concentrators automatically. |
| Service name | string; default: none | The Service Name to connect to. Leave empty to detect Service name automatically. |
Multi-APN
{{{name}}} supports Multiple PDN feature in order to establish connections to multiple mobile networks using a single SIM card. You can find a configuration example here.
IPv6 Settings
The IPv6 Settings section is used to set up some of the more specific and less frequently used interface parameters. This section is different for each protocol.
IPv6 Settings: Static
Advanced Settings information for Static protocol is provided in the table below.
| Field | Value | Description |
|---|---|---|
| Delegate IPv6 prefixes | off | on; default: on | Enable downstream delegation of IPv6 prefixes available on this interface. |
| IPv6 assignment length | Disabled | 64 | Custom; default: Disabled | A metric specifies the priority of the gateway. The lower the metric, the higher the priority (0 for highest priority). |
| IPv6 address | IPv6 addresses with or without mask prefix are accepted; default: none | Assigns an IPv6 address for this interface. CIDR notation: address/prefix. |
| IPv6 gateway | IPv6 addresses are accepted. E.g. ::0000:8a2e:0370:7334; default: none | IPv6 default gateway. |
| IPv6 routed prefix | IPv6 addresses with mask prefix are accepted E.g ::1/128; default: none | Public prefix routed to this device for distribution to clients. |
| IPv6 suffix | Allowed values: "eui64", "random", fixed value like "::1" or "::1:2"; default: none | Optional. Allowed values: 'eui64', 'random', fixed value like '::1' or '::1:2'. When IPv6 prefix (like 'a:b:c:d::') is received from a delegating server, use the suffix (like '::1') to form the IPv6 address ('a:b:c:d::1') for the interface. |

| Request IPv6-prefix of length | integer [0..64] | Automatic | disabled ; default: Automatic | Defines how this will request a IPv6 ULA-Prefix length. If set to 'disabled' the interface will obtain a single IPv6 address without a subnet for routing. |

| Field | Value | Description |
|---|---|---|
| Delegate IPv6 prefixes | off | on; default: on | Enable downstream delegation of IPv6 prefixes available on this interface. |
