I have an extra pc that isnt being used(amd3800/2gig) and I recently set it up as a dns server using the trial version of simpledns, this really improved internet loading times. I started doing some research and found out about Smoothwall and IPcop and how you can use an extra PC and a few NICs as a high performance router/firewall/ dns server. I have a simple home network which consists of a fast 25down/5up cable connection, Dlink DI-634 router, Vonage VOIP box, 2 wired PCs and one wireless laptop. I was thinking I could setup Smoothwall on the extra PC and use the Dlink as an AP for my laptop. Would this improve my overall network performance? Im mainly interested in improved performance for P2P and internet surfing as well as QOS for my VOIP and a better firewall. So what do ou guys think?? Will Smoothwall on a AMD3800 perform better then my Dlink DI634 which is a very god performer??
thanks

Running a linux firewall on your old hardware is much more secure than your Dlink. Your dlink probably states that it's got SPI (stateful packet inspection) and that's probably true for TCP applications but doesn't do squat for UDP applications. You can't control packets entering/leaving your network based on TCP flags. The IPtables firewall gives you better logging capabilities, more granular control of systems access, VPN capabilities, etc, etc, etc. Some flavor, i.e. Smoothwall, IPCop even has web interface so you don't have to write out your firewall rules the old fashion way.
