Thank you all for your answers, and for taking the time to help me out. i appreciate it.

I'm sorry for not giving the full details of it, so here it goes:

My main objective is to have a secure network, and also learn how to set it and learn with it.

Mainly the "old box" is a P2 133Mhz, with 64MB ram, with a 2gb HD.

The other 2 computers are both running Dual Boot (Windows Xp, SlackwareLinux), but mainly i use Linux, yes i have some knowledge in linux, and i've got a lot of books to help me out too.

As for the budget it's kind of a medium one, i mean i don't want to spend a lot of money on it, but i also don't want the minimum as possible.

And for the connection it's a 256K cable connection.

So what do you guys think i should do, put on smoothwall with 2 NIC, or buy a router with firewall and put like IKnowNot said: put the "old computer" with snort? any other opinions?

What would you do if this was your case?

If any other details are necessary, just tell me.

Thanks in advance,
