The information in this page is updated in accordance with firmware version RUTX_R_00.07.04.5.


The LAN page is used to create and set up local area network interfaces.

This manual page provides an overview of the LAN windows in RUTXR1 devices.

LAN Configuration

The LAN Configuration section displays LAN interfaces currently existing on this device.

Field Value Description
IPv4 address ip4; default: 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: 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.
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.

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.

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 IP integer [1..255]; default: 100 The DHCP server's IP address range start value.
End IP integer [1..255]; default: 150 End IP, i.e., the last possible IP in the selected range for the DHCP server.
Lease time integer [1..999999]; default: 12
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 measurement units.

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