Hi,

while performing a LiveCD gentoo install, I have a network setup question.

Let's take my PC as an example. I boot with LiveCD and my NIC is automatically detected.
I follow gentoo handbook for network manual setup, but I never applied this setting:

"default gw" points to the first router you need to find to get to the outside world.

ie: On the machine I'm on, my IP is 192.168.0.2, another machine in the building is connecting me to the internet, and it's IP is 192.168.0.1, hence I do a "route add default gw 192.168.0.1", as it is my gateway to the internet.

When you start your pc, it gets an IP and route etc from your DSL router automagically. Check it by typing "route". My output here shows:

If you don't have a gateway address assigned, your PC will still operate fine on your local network, you just (technically) won't be able to access anything outside of your network (like the Internet). Can you access the Internet right now? If you can, what stage of the install are you on? You might be retaining the default gateway from when the LiveCD grabbed info from DHCP that your router most likely is putting out.

Explanation:
route: manipulates the kernel's routing table. You need to use the route command when you have any static routes (routes not configured through DHCP). If you assign a static IP address to your machine, you may have to use the route command so that your machine knows where to go to access the network (this is usually set through the gateway variable in the /etc/conf.d/net file).

Current settings:
You can use the netstat command to query your current route settings:

Hi,

Here is my summary to understand if I got it for now.

I am connected to the Internet (ADSL) via a D-Link (ADSL Router with 4 Switch ports at 10/100Mbps).
It acts as default gateway and its address is 192.168.1.1
It also acts ad DHCP and ranges from 192.168.1.100 to 192.168.1.110

My PC IP address I decided to set it statically to 192.168.1.100

Therefore, my net configuration file is:

You are correct, by writing to your /etc/conf.d/net file, you remove the requirement to issue the command you mention.
