I originally set up a Fedora 5 Linux box which worked reasonably well. I had some traffic shaping and a limited number of ports open. However it was getting out of date (we’re now on Fedora 9) and I heard good things on the Ubuntu UK Podcast about IPCop, a firewall-only Linux distro.
I have now installed IPCop. It does have some security improvements over my existing set-up, although it doesn’t double-up very well as a mini server since it only includes the parts of the OS required for a Firewall. I think I’ll have to move my Subversion server onto my MythTV box which is always on – although I’m now tempted to give GIT a try, which I’ve also heard good things about.
I think I may have another issue which is muddying the waters as far as my firewall goes. Previously I had very bad connectivity with the old firewall, which went away after a few weeks. When I first set up the new IPCop firewall, I had the same problem, which now seems to have gone away too. It may be just freak network traffic. It may be I have a dodgy network adaptor in the machine (one of the four). More research is required…
