Share LAN internet connection over wifi PCI card.

[beerisgoodmate]

Hi All,

My Gentoo box is connected to the internet over lan.

I have a wifi card I wish to share the internet with.

Any tips on how to do this?

Cheers

1st you need to configure your Wireless card
2nd you need to have iptables rules in place to forward internet traffic across the interfaces.


can you please post your:
ifconfig
ifconfig -a
iptables -L

Hi Dagger, thanks for the reply.

ok assuming your your internet uses class A network 10.x.x.x you can use class C network for your other computer (192.168.1.x should do, but can be any other one)

I assume this is very "lazy" setup as you trust your users on the wifi site.

Yes you have to assign a static IP for your wireless

of course your kernel needs to support relevant options from "Core Netfilter Configuration". It's save to mark ALL of them as modules. From your logs it seems it doesn't at the moment.

if you go to /usr/src/linux and run
make menuconfig
go to:
Networking -> Networking Options -> Network packet filtering ramework (Netfilter) -> Core Netfilter Configuration -> select all as modules
and
Networking -> Networking Options -> Network packet filtering ramework (Netfilter) -> IP: Netfilter Configuration -> select all as modules
than exit menuconfig and save configuration
