I currently connect to the net from my PC which has a directly connected USB modem, This machine is also configured to run a firewall and to be the ICS master (running XP SP2) the other machines on my lan (currently 3) have the first one defined as their gateway and router. This all works at the moment.
I want to reduce the load on my PC by shifting the internet handling onto a seperate machine, I have several older ones laying about and I figured that I would load one of the linux distros designed specifically for the job.
The problem I have is that there are several and I don't know which one to choose, I'm an experienced unix/linux sysadm and one of the other machine on the lan is a redhat 9 server, if that helps.
so far I've found:
and I know there are others. My top priority is security as getting through the firewall would open up my entire lan, then stability and then ease of use. I must be able to VPN from my XP PC to client sites.
The spare machines are pretty low spec, P1 or P2, etc. about 4 years old. so some idea of realistic hardware requirements would also be useful.
