I'm currently running a server at home with Fedora, and I think i've decided to move to Centos to save on the updates (and try something new, but not too different).
Whilst I make the move (also to a different machine to make things a little easier), I'd like some advice or direction on the following idea:
I'm fairly familiar with using an old PC set up running IPCOP, it works great, just an in/out network setup. My thoughts are, could I consolidate the functionality provided by the IPCOP machine onto the Centos machine??
So, the machine i'm, going to load my new CENTOS setup onto has 2 network interfaces, currently one will be spare. Rather than having the spare, can I connect it to the modem and make the CENTOS machine provide IPCOP-like service to the other network interface facing the internal home network? I've tried to illustrate this with the attached pic incase this is unclear - the proposed change in red.
Features I like in IPCOP - traffic shaping, spamassasin, dhcp, firewall, vpn, snort, the web interface.
Any cons on security for a server doubling up to do this?
Thanks in advance!
