IPv4 LAN Configuration on RV180 and RV180W


The LAN Settings page allows you to configure the LAN interface of the router. The default settings would be sufficient in most of the cases. This article explains how to configure the LAN settings on RV180 and RV180W.

Applicable Devices

• RV180
• RV180W

Configuration of IPv4 LAN Settings

Step 1. Using the Configuration Utility on the router, choose Networking > LAN (Local Network) > IPv4 LAN (Local Network) which opens the IPv4 LAN page.

Step 2.  Under the Network sub-title, enter the following:

• Host Name — Enter the name for the router. Also, it can be modified. If the name is altered, the device will ask for a reboot which closes all the existing sessions and it takes approximately 115 seconds to come up again.

Step 3.  Under the LAN(Local Network) Configuration, enter the following relevant data:

Note — If the LAN IP address is changed, the browser will not respond when the Save button is clicked to apply the changes. The new IP address must be used to reconnect to the configuration utility. For example, if the LAN TCP/IP address is changed from to, then the IP address of the computer connected to the router must be changed(or release and renew IP address if connected via DHCP) so that it is in the subnet. Then use in the browser to connect to the utility.

• IP Address — Enter the IP address of the device.

• Subnet Mask — Enter the subnet mask for the above IP address.

Step 4.  By default the router will function as a DHCP server which provides TCP/IP configuration to the devices connected to the router. Under the DHCP, enter the following data:

• DHCP Mode— Choose one of the following three options from the DHCP mode drop down menu.

– None — Choose this option if the computers in the LAN are configured with static IP addresses or are configured to use another DHCP server. Click Configure Static DHCP button which takes to the static DHCP configuration page.

– DHCP Relay — If selected, enter the relay gateway information in the Relay Gateway field.

– DHCP Server — Choose this option from the drop down to use the router as DHCP server and enter the following information .

• Domain Name— Enter the name of the domain(Optional).

• Starting IP address — Enter the IP address of the first host in the range. Any new DHCP client joining the LAN will be assigned with an IP address which is between this IP address and the ending IP address.

• Ending IP address — Enter the IP address of the last host in the range. Any new DHCP client joining the LAN will be assigned with an IP address which is between starting IP address and this IP address.

• Primary DNS Server — Enter the primary DNS server IP address.

• Secondary DNS Server — Enter the secondary DNS server IP address.

• Lease Time — Takes a value between 1 and 262800 which indicates the number of hours an IP address is leased to clients.

• Relay Gateway — Enter the relay gateway address if DHCP Relay is selected in the DHCP mode drop down menu.

Step 5.  Under the LAN (Local Network) proxy, configure the following:

• DNS Proxy — Check the DNS Proxy check box to enable DNS proxy on this LAN or un check to disable it. When this feature is enabled, the router will act as a proxy for all DNS requests and communicate with the ISP's DNS servers(as configured in the WAN settings page). All DHCP clients will receive the primary/secondary DNS IP along with the IP where the DNS proxy is running, i.e. the box's LAN IP. All DHCP clients will receive the DNS IP addresses of the ISP excluding the DNS proxy IP address when it is disabled. The feature is particularly useful in Auto Rollover mode. For example, if the DNS servers for each connection are different, then a link failure may render the DNS servers inaccessible. However, when the DNS proxy is enabled, the clients can make requests to the router and the router, in turn, send those requests to the DNS servers of the active connection.

Step 6.  Click Save to save the settings, or click Cancel to abort changes.

Note: This page provides information and configuration of default LAN. The default VLAN ID will always be "1" for default LAN.
