I have an old 133 mhz computer with a gig hard drive just sitting in my room and I got to thinking that I either want to turn it into a firewall or a honeypot.

I got it set up on the DMZ (currently running WIN98) but I want to go Linux or BSD on it

In your peoples opinion what is the best distro of linux or to use with a gig hard drive and 80mb ram to use for a firewall or honeypot..

Or I am not sure would any of the open or free BSD's work good for this task and do i have enough space to use them.

Just looking for opinions so I can do some research and have my own,

Thanks
