Networking Linux with Windows

[overturfa]

I am currently running one Linux box with Mandrake 8.2

The Idea is to use this Linux box as an internet gateway and network addressing server for my other windows boxes I got the Linux box connected to my cable modem on eth0, and to a hub on eth1. The Linux box has internet connectivity, but I am haveing trouble sharing the internet connection with my windows boxes. I have two NIC cards in the Linux box and from what I can tell they are both working properly

I am able to ping the Linux box from the Windows and pull IP's from it using winipcfg.
The windows boxes show the correct subnet mask for the eth1 (LAN) card on the Linux box and they show the IP address for that same card as the gateway. From my experience using ICS in a windows only environment, this seems correct. However, when I open a browser on one of the windows boxes, it times out.

I used the drakex wizard to configure the Linux bos for ICS so it's very possible that it misconfigured something but I dont' know what it could be.

Any advise on this matter is appreciated.

Thanks In Advance,
Adam

I know zero about the Mandrake setup, but it sounds like it is just doing DHCP addressing with IP masquerading. Hopefully someone else here will be able to help you out with the particualrs of that specific software.

My first guess would be that this is probably a port forwarding issue. Could be that the linux box's firewall is blocking port 80 so that machines behind the linux box can't see the internet.

If your just using this box for a gateway, I would suggest downloading and installing smoothwall. It will be much simpler and after a little reading of the very well written manuals you will be much happier. The only problem is that this machine will be effectively unusable for anything but a firewall/router, but IMHO that is a good thing.

Thanks for the post. I e-mailed a friend of mine who explained the whole IP masquerading thing to me and it helped out. I managed to get things working. It turned out that the masquerading was improperly configured. Somehow eth0 was set to masquerade behind its self and that was the problem.

I checked out the smoothwall program too. Pretty cool, but I also want to run a dedicated Half Life server from the Linux box.

Thanks for the reply though!
Cheers,

Adam.
