3.4. Installilng TCP/IP on your Network Workstations

The computers on your network must use the TCP/IP protocol to communicate with NetProxy. TCP/IP is the network protocol used by computers on the Internet. If you are using Windows 95, Windows 98 or Windows NT, you can safely install the TCP/IP protocol alongside any existing network protocols such as NetBEUI or IPX/SPX.

The TCP/IP protocol is available for all popular operating systems including Windows, OS/2, all variants of UNIX, MacOS, BeOS, AmigaDOS and RiscOS. All of these operating systems can be configured to use NetProxy as a gateway to the Internet.

IP addresses beginning 192.168 are reserved for use on private networks and will not clash with IP addresses of valid hosts on the Internet. We therefore recommend that you use IP addresses in the range 192.168.0.1 to 192.168.0.254 for the machines on your network.

There are two methods of assigning IP addresses to network clients. You can either instruct your network computers to obtain an IP address from a DHCP server (NetProxy will then take care of assigning appropriate IP settings to your computers), or you can configure the settings for each machine manually.

To install TCP/IP on a machine running Windows:-

• Run control panel and select the ‘Network’ icon.
• In the network Window, highly the entry for your network adapter and select the ‘Add…’ button.
• Select ‘protocol’ to add a new protocol for your network card and click ‘Add…’.
• In the ‘Manufacturers’ list box, select ‘Microsoft’ and in the network protocols list box, select ‘TCP/IP’ and click OK.

To configure a machine running Windows to use DHCP to automatically obtain TCP/IP settings from NetProxy:-

• Run control panel and select the ‘Network’ icon.
• In the network Window, highly the entry for the TCP/IP protocol bound to your network adapter and select the ‘Properties’ button.
• Select the ‘IP Address’ tab and ensure that the option to “Obtain an IP Address Automatically” is selected.
• Click OK to close all of the network settings dialogs. You may be asked to reboot the computer.

When the computer reboots, assuming NetProxy is running on another machine on your network, a unique IP address and related TCP/IP setup details will be automatically assigned.

To manually configure the TCP/IP settings on a machine running Windows 95, 98 or NT:-

• Run control panel and select the ‘Network’ icon.
• In the network Window, highly the entry for the TCP/IP protocol bound to your network adapter and select the ‘Properties’ button.
• Under the IP Address tab, select ‘Specify an IP address’ and type the next available IP address (for the first PC, this would usually be 192.168.0.2), and type 255.255.255.0 in the subnet mask box.
• Under the DNS configuration tab, select ‘Enable DNS’ and add a DNS server entry containing the IP address of the NetProxy PC (this would usually be 192.168.0.1 if you have followed the instructions given in this document). You may also have to provide a unique host name for the computer (this can be anything, as long as it is unique to your network).

You may be required to restart the computer in order for the new TCP/IP settings to take effect.

Once you have configured your client software to use NetProxy, the setup is complete.
