The OfficeServer allows you to configure various settings for connecting to the network, and connecting to the NetWinder. Together, these options are called the Network Settings.

You can reach the main Network Settings web page by clicking Network from the Administration page.

The ethernet settings affect how your NetWinder connects to its local ethernet network. If you have a cable or DSL modem or an external router to the internet, you will also use ethernet settings to configure internet access.

Firewall settings restrict access to your NetWinder from certain sites on the internet. If your NetWinder is acting as a router, you can also block certain sites from reaching others through the router.

If your NetWinder is acting as a router, you can also use Port forwarding settings to redirect requests from one server to another.

The DNS server is responsible for converting Internet domain names, like www.rebel.com, into IP addresses, like 192.168.42.43. You can set up your own name-to-address mappings in the DNS configuration.

Your NetWinder has a serial port to which you can attach an external modem used to connect to the internet through any standard internet service provider. To do this, use the PPP dialer configuration screen.

To share your NetWinder's files with Windows, Macintosh, and UNIX computers, you will need to use the file sharing configuration panel.

Ethernet Settings

Your NetWinder has two ethernet interfaces: a 10/100 Mbit ethernet, called eth1, for communicating with local workstations, and a second 10 Mbit ethernet, called eth0, for optionally communicating with a cable/xDSL modem or an external router.

The ethernet configuration page looks like this:

If you click on Change these parameters, you will then see the following page:

It consists of three parts: Network Parameters, Eth1 Parameters, and Eth0 Parameters.

The Network Parameters section allows you to change the following options for the entire NetWinder:

The Eth0 and Eth1 Parameters sections allow you to change the following options for each ethernet device:

When you have finished making changes, press the Submit button to make them permanent.
