OK, no need to open another thread... why don't you follow advices given to you in the one you already started ?
See here:
http://forum.avast.com/index.php?topic=15536.msg131057#msg131057Again... Smoothwall can not be your hardware router/firewall if it's installed in your computer. You need another computer, for example, some old spare PC that you don't use any more. Then, you fill that PC with Smoothwall, configure it properly, install that computer (now turned into hardware firewall) in between your modem and your primary PC and you're good to go...
The problem is, as far as I can see, you are totally unfamiliar with those things, and you are running into things without carefully checking them first. I'm trying to give you an advice just to spare you additional problems that you will, most likely have after those actions you already started to perform on your own.
As I suggested in that thread, easiest way for you is to go and buy some of those small router/firewalls, they are pretty cheap. Around 25-35, and even if you want something more expensive, you can pay around 90-120 dollars... depends on what do you really need. D-Link and LinkSys routers are the best of the best, and very easy to install and setup. You have to agree that it would be much, much less expensive thing than going to buy another PC just to turn it into firewall
. However, that is a very good idea, but just in case you have some spare old computer that no one in your house uses any more... of course, it has to be in good condition, but Smoothwall is not demanding, so it doesn't have to be some speciall, hi-end configuration... I believe that you can run it very well even on some slower, older systems without a problem...
Cheers !
