Interfaces: if_name #

This section covers all parameters directly related to a network interface.

General Setup #

The General Setup section is used to configure the protocol and all the different parameters that go along with each protocol. This section is different for each protocol.

General Setup: Static #

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

Networking rutos manual interfaces network interfaces lan general setup static ip v1.png
FieldValueDescription
IPv4 addressip4; default[for LAN]: 192.168.1.1The IPv4 address interface of this interface. An IP address identifies a device on a network and allows it to communicate with other devices.
IPv4 netmasknetmask; default[for LAN]: 255.255.255.0The 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 gatewayip4; default: noneThe IPv4 gateway address used by this interface. An interface’s default gateway is the default address through which all outgoing traffic is directed.
IPv4 broadcastip4; default: noneThe 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 serversip4; default: noneDNS 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 Setup: DHCP #

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

Networking rutos manual interfaces network interfaces lan general setup dhcp v1.png
FieldValueDescription
Hostname to send when requesting DHCPstring; default: noneA hostname for this interface used to identify this machine on the DHCP server.
General Setup: DHCPv6 #

The DHCPv6 protocol is used to set up an IPv6 interface which obtains its configuration parameters automatically via a DHCP lease.

Networking rutos manual interfaces network interfaces lan general setup dhcpv6 v1.png
FieldValueDescription
Request IPv6-addresstry | force | disabled; default: tryDefines the behaviour for requesting an address.
Request IPv6-prefix of lengthinteger [0..64] | Automatic | disabled ; default: AutomaticDefines 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.
General Setup: PPPoE #

The PPPoE protocol is used to set up a PPP (Point-to-Point Protocol) connection over the Ethernet port.

Networking rutos manual interfaces network interfaces lan general setup pppoe v1.png
FieldValueDescription
PAP/CHAP usernamestring; default: noneUsername used in PAP/CHAP authentication.
PAP/CHAP passwordstring; default: nonePassword used in PAP/CHAP authentication.

FieldValueDescription
ModeNAT | Bridge | Passthrough; default: NATMobile 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 RUTX11 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 RUTX11 instead of LAN IP. Using Passthrough mode will disable most of the device’s capabilities.
PDP TypeIPv4 | IPv6 | IPv4/IPv6; default: IPv4Specifies what of address will be requested from the operator.
SIMSIM1 | SIM2; default: SIM1Select which sim will be used for this interface.
Auto APNoff | on; default: onThe 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 APNstring; default: noneAn 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;.gprs;it cannot end in:and it cannot contain the asterisk symbol (*).
Authentication TypeNONE | PAP | CHAP; default: NONEAuthentication method that your GSM carrier uses to authenticate new connections on its network. If you select PAP or CHAP, you will also be required to enter a username and password.
Bridge | Passthrough: MAC Addressmac; default: noneSpecifies 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.

DHCP Server #

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.

In order to view the DHCP server configuration, the interface protocol must be set to Static.

DHCP Server: General Setup #

The General Setup section is used to set up the main operating parameters of the DHCP server.

Networking rutos manual interfaces network interfaces lan dhcp server general setup v1.png
FieldValueDescription
Enable DHCPEnable | Disable | DHCP Relay*; default: EnableTurns 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.
Startinteger [1..255]; default: 100The starting IP address value. e.g., if your device’s LAN IP is 192.168.1.1 and your subnet mask is 255.255.255.0 that means that in your network a valid IP address has to be in the range of [192.168.1.0..192.168.1.254] (192.168.1.255 is a special unavailable address). If the Start value is set to 100 then the DHCP server will only lease out addresses starting from 192.168.1.100.
Limitinteger [1..255]; default: 150How many addresses the DHCP server can lease out. Continuing from the example above: if the start address is 192.168.1.100 and the server can lease out 150 addresses, available addresses will be from 192.168.1.100 to 192.168.1.249 (100 + 150 – 1 = 249; this is because the first address is inclusive).
Lease timeinteger [2..999999]m/h; default: 12hA 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.

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