Configuring IPv4 LAN (Local Network) Settings

Configuring the Host Name

To configure the host name of the Cisco RV180/RV180W:

  1. Choose Networking > LAN (Local Network) > IPv4 LAN (Local Network).
STEP 2 In the Host Name field, enter the host name of the Cisco RV180/RV180W. You can use only alpha-numeric characters and the hyphen.

The default hostname (for example, “router6DE44E”) consists of the word “router” followed by the last 3 bytes of the router’s LAN MAC address (in hexadecimal form). This format allows the FindIT application to use Bonjour to identify Cisco Small Business devices on the LAN.

NOTE: Changing the router name causes the router to reboot.

  • Configuring the IP Address

    You might want to change the default IP address (for example, if the default address is already assigned to another piece of equipment in your network).

    To configure the IP address of the Cisco RV180/RV180W:

    1. Choose Networking > LAN (Local Network) > IPv4 LAN (Local Network).
    2. Enter this information:
    3. IP Address

      Enter the LAN IP address of the RV180/RV180W.

      Make sure the address is not in use by another device on the same network. The default IP address is 192.168.1.1.

      Subnet mask

      Choose the subnet mask for the new IP address from the drop-down menu. The default subnet is 255.255.255.0.

    STEP 3 Click Save.

    After changing the Cisco RV180/RV180W’s LAN IP address, your PC is no longer connected to the Cisco RV180/RV180W.

  • To reconnect your PC to the Cisco RV180/RV180W:
  • Open a new browser window and enter the new IP address of the Cisco RV180/ RV180W to reconnect.
  • Configuring DHCP

    By default, the Cisco RV180/RV180W functions as a DHCP server to the hosts on the Wireless LAN (WLAN) or LAN network and assigns IP and DNS server addresses.

    With DHCP enabled, the router's IP address serves as the gateway address to your LAN. The PCs in the LAN are assigned IP addresses from a pool of addresses. Each address is tested before it is assigned to avoid duplicate addresses on the LAN.

    For most applications, the default DHCP settings are satisfactory. If you want another PC on your network to be the DHCP server, or if you are manually configuring the network settings of all of your PCs, disable DHCP.

    To configure the DHCP settings of the Cisco RV180/RV180W:

    1. Choose Networking > LAN (Local Network) > IPv4 LAN (Local Network).
    2. From the DHCP Mode drop-down menu, choose one of these options:
      • None—Choose this option if the Cisco RV180/RV180W is not going to act as a DHCP server.
      • DHCP Server—Choose this option to configure the Cisco RV180/RV180W to be a DHCP server and enter this information:
        • Domain Name— (Optional) Enter the domain name for your network.
        • Starting IP Address/Ending IP Address—Enter the first and last of the contiguous addresses in the IP address pool. Any new DHCP client joining the LAN is assigned an IP address in this range. You can save part of the range for PCs with fixed addresses. These addresses should be in the same IP address subnet as the Cisco RV180/RV180W's LAN IP address.
        • Primary DNS Server/Secondary DNS Server—DNS servers map Internet domain names (for example, www.cisco.com) to IP addresses. Enter the server IP addresses in these fields if you want to use different DNS servers than are specified in your WAN settings.
        • Lease time—Enter the duration (in hours) for which IP addresses are leased to clients.
      • DHCP Relay—Choose this option to configure the Cisco RV180/RV180W to be a DHCP relay agent and enter the address of the remote DHCP server in the Remote DHCP Server field. The relay agent transmits DHCP messages between multiple subnets.
    3. Click Save.

    Configuring the DNS Proxy

    You can also enable a DNS proxy. When enabled, the router then acts as a proxy for all DNS requests and communicates with the ISP's DNS servers. When disabled, all DHCP clients receive the DNS IP addresses of the ISP.

    To configure the DNS proxy server for the Cisco RV180/RV180W:

    1. Choose Networking > LAN (Local Network) > IPv4 LAN (Local Network).
    2. In the DNS Proxy field, check to enable the Cisco RV180/RV180W to act as a proxy for all DNS requests and communicate with the ISP's DNS servers.
    3. Click Save.
