Set Up Your Own Free DSL/ Broadband Router Using Windows XP Professional
Suppose you set up two home networks or local area networks (LAN) at a small office and want also to connect one network to another. To do this you have to buy a router or until after you can purchase one you can get around this by creating “free router” from the existing computer.
What is router? a router is a network device that serves to connect two or more computer networks and channel data from one computer to another within a network. Routers are also used to connect smaller networks to larger one and are also used to divide large networks into smaller ones
Now let’s get to the point. You have a computer connected to DSL / broadband connection and run two networks (let’s say Network 1 and Network 2) at your office and you wish to connect all computers within both networks to access the internet or simply share files or printers between the two networks. You can make the computer that connect to the internet a simple router and what you need is a computer installed with Windows XP Professional, three Local Area Network cards (NIC) , a switch or hub (whichever is applicable).
Step One : Enable IP Forwarding on Windows Registry
Before you proceed make sure you first back-up you Windows registry just in case you mess up with it.
The first thing you do is to enable IP forwarding on the computer you want to make a router. Go to Start and click Run then type in regedit to run registry editor and locate the the following registry key.
- HKEY_LOCAL_MACHINESYSTEM/CurrentControlSet/Services/TcpipParameters
- Right click IPEnableRouter registry object, and click Modify. Change IPEnableRouter window registry value to 1 and then and click OK, close the registry editor and reboot your computer.
Step Two : Configure Router For First LAN Card (Network I)
Go to Control Panel, select Network Connections, right click on the first LAN Card and then select Properties.
On the General tab, select Internet Protocol (TCP / IP), select Properties and assign it with the following profile :
Network Card I (connect to network I):
IP: 10.10.10.1
Netmask: 255.255.255.0
Gateway : leave it blank
Step Three : Configure Router For Second LAN Card (Network 2)
This second step is similar to the first configuration except for the IP address configuration :
IP: 192.168.20.1
Netmask: 255.255.255.0
Gateway : leave it blank
Step Four : Configure all the client computers with following profile.
Network 1
IP: 10.10.10.2-254
Netmask: 255.255.255.0
Gateway : 10.10.10.1
Network 2
IP: 192.168.20.2-254
Netmask: 255.255.255.0
Gateway: 192.168.20.1
To make sure you have successfully set up a working connection between the two networks run a ping command from a workstation computer in network 1 and nerwork 2
