This
tool configures your system so that it acts as a gateway to the
Internet for other machines connected to it via a LAN. In
order for your machine to do this, you will need an already
configured and working connection to the Internet and a network
connection to your LAN. This implies at least two interfaces,
for example, a modem and an Ethernet card.

This wizard will also configure a firewall to block most connections from the Internet. You are encouraged to check that the firewall configuration suits you after completing the wizard. |
After you complete this wizard, all computers on the LAN will be able to access the Internet. Their configuration will be automated thanks to the DHCP server that will be installed on your gateway, and the Web access will be optimized thanks to the use of the squid transparent proxy cache.
Choosing the Internet Interface
You first need to specify the name of the interface connected to the Internet. Make sure you select the correct one: use the examples in the on-line help as a guide.
Choosing The LAN Network Adapter
If you have more than one Ethernet interface, the wizard will ask you to choose the one connected to your LAN. Make sure you select the correct one. Note that all traffic to and from this network passing through the gateway will be masqueraded.
Configuring The LAN Interface
At this point, if the LAN interface has not been previously configured, the wizard will automatically install and setup all the software needed for the gateway to function properly.
Otherwise, in the situation where your interface has been previously configured, the wizard will offer to reconfigure the LAN interface so that it will be compatible with the gateway services. It is recommended that you leave the options at their defaults and click on the button.
A DHCP server has been installed on the machine. By configuring the clients on the local network to use DHCP, they will automatically use the Mandrakelinux machine as a gateway to the Internet. This works for Windows, GNU/Linux and any other OS that supports DHCP.
For example, on a Mandrakelinux client system, check the box when configuring the network as shown in Figure 4.6, “Configuring a Client to Use DHCP”.
