I'm running Potato with a 2.2.14 kernel. Is it possible to use Ipchains to firewall a single machine?
The various documents on Ipchains which I have read (and can't understand anyway) seem to assume that the firewall will be on its own machine and talks in terms of two network cards. I have a small network (3 machines) at home and I have a modem in one machine which is the only machine that will access the internet. The other machines will not be accessing the internet in any way. Can I setup Ipchains on the single machine to act as a firewall. I think that what I need is a packet filter. As far as firewalls/Ipchains goes I am a complete idiot beginner ( I can produce certificates ) so _please_ keep the hints simple. I have tried Mason and that seems to create rules that incorporate my IP address which may change each time I log on via my ISP. So I can't see how that will work. I have compiled the various appropriate options into the kernel. I could, at least, understand that much. I want to make my machine secure from outside interference when I'm on the internet.
