Configuring WAN Settings for the WebPort

NOTE

When assigning IP addresses across the system, (WAN, LAN, NAT, Forwarding) DO NOT overlap with IP addresses used elsewhere. For example, setting a Static WAN address to the same forward facing address used for a NAT entry will result in you having to reset to defaults.

NOTE

Keep the following in mind:

  • If you configure the WebPort's WAN port as a DHCP client, the WAN IP address is allocated by the DHCP server on the network to which you connect the WebPort. You do not need to change the address.
  • If you configure the WAN port with a Static IP address, you must specify the appropriate IP address, subnet mask, gateway, and one or two DNS addresses for your network.

NOTE

To minimize networking issues during initial setup, it is recommended that you connect to the WebPort for the first time using the LAN interface. The LAN interface on the WebPort, by default, is configured as a DHCP server. This means that as long as your PC is configured as a DHCP client, it will receive an IP address automatically from the WebPort.

The WebPort WAN port is a single Ethernet port that provides an interface between a network and the WebPort. You can access the WebPort User Interface over the network via its WAN Ethernet port (as well as locally via cell modem or LAN interface). Each WebPort WAN port is assigned a unique Spectrum Controls MAC address. This address is listed on the label on your WebPort. During setup, you can configure the WAN as a DHCP client or with a static IP address. The WAN port communicates at 10/100 Mbytes per second over an Ethernet connection.

You may also configure a WebPort using an Ethernet cable to make a connection between a network and the WAN port on the WebPort front panel. You may use either a straight-through or crossover cable as the WebPort autosenses which cable is used. Before you can communicate with the WebPort, the user-supplied power supply needs to be wired into the PWR terminal strip on the WebPort front panel, and plugged into an outlet in a controller cabinet or other power source. Once power is applied to the WebPort, the WebPort starts up and initially configures itself to communicate by acquiring a WAN IP address from the network to which you connect it. Once the WAN IP address is acquired, it is displayed on the WebPort display. The LAN IP address displayed on the WebPort display is a hard-coded, default value. It can be changed to the user’s choice using Configure:LAN Settings. You can also access the WebPort user interface by connecting a PC to the LAN. The LAN defaults to being a DHCP server. The default address of the WebPort on the LAN is 192.168.2.1.

To configure WAN settings for the WebPort:

  1. From the Configuration Work Area, select the following icon: This is a picture of the dialog. The Network Setup dialog appears: This is a picture of the dialog.
  2. View or specify the following WAN Settings options:
    • Connection type. Identifies whether to use static or dynamic address configuration for the WAN network:
      • Static IP. Select this option if you want the Ethernet IP address for the WebPort to be static. This means that the IP address is entered manually and does not change. Example: 10.0.0.151
      • DHCP Client. If you have a DHCP Server installed and configured on the network, select this option to allow the WebPort to get a WAN IP address from the designated DHCP. A WebPort, connected to another WebPort configured as a DHCP Server can also be designated a DHCP client. If you have selected Static IP for the WAN, additional options will be shown.
    • WAN IP. Select a valid Static IP address in the Network. Enter WebPort WAN IP Address. Example: 10.0.0.2 This is a picture of the dialog.
    • Subnet Mask. Enter subnet mask address. This value is typically 255.255.255.0.
    • Gateway. Enter Gateway address. Example: 10.0.0.1.
    • DNS1. Enter the primary DNS value. This option is enabled only if you select Static IP addressing.
    • DNS2. Lists a secondary DNS value. For the WebPort, this value may be set to a different value. If the primary connection fails, the secondary is available. If you do not wish to use the Google DNS address, try Google's Namebench to determine which public DNS server will best suit your purposes.
    • Submit. Saves data on WebPort and exits.
    • Cancel. Exits without saving data from WebPort.
