Internet on Home Network Set-up

Tags:

First off, I have a pitiful amount of experience with setting up networks.

I am trying to set up a network in my house among 5 or so computers.

Basically, I have a PPP based internet connection via wvdial(ppp0) that I'd like to share to the other computers in the house over ethernet (eth1).

I have a working DHCP server installed on the computer with the internet connection.

How would I go about getting the internet to work?

I'm assuming netmasquerading, but I have trudged through mountains of documentation and cannot figure this out.

The key thing you're missing is, as you note, the various IP masquerading/firewall commands to both protect your LAN, and to do the NAT/masquerading.

You can dig into the GNU/Linux networking and firewall stuff to craft your own script. But Debian includes some firewalls that do all that for you and are much easier.

Just install one. With something like FireStarter (requires GNOME libraries and a GUI) you'll be up and running in less than 5 minutes.

Nevermind, Firstarter is very good at what I'm trying to do.

But it ate my dhcpd.conf, and the one it made doesn't work, DHCPD3 rejects it. Blah, more time to work I suppose. Guess I should back up my configs more often than I like to think that I do.

Solved:

I needed to set the default gateway on the client computers.

But, is using /sbin/route a permanent change? Do I need to add the changes to an init script?

Alright, the *nix computers are all working fine, but the Windows (Vista, even) based computer is showing "unknown network" and showing that it is local only (no internet access).

I'm well aware that this verges on blasphemy, but does anyone know how to configure my server to play nice with the Windows compy?
