``Real Routing'' is usually not necessary on broadband connections since they use a single static route for everything outside the LAN. In fact, having things like RIP running around on an internal LAN can thoroughly confuse some things like the routed program on SCO OpenServer. The average broadband connection simply doesn't have the bandwidth to tax most PC architecture machines. Our first routers were MorningStar 501s, which were '386 based running some BSD clone from flash, and they handled a T1 adequately. Our current ``router'' is a PII 266 running Linux with a Sangoma WAN card connected to our T1. The load average is pretty constant at 0.00 with 99.2% idle time even though there are about 400 ipchains rules in play. If you're planning on using IPSec VPN tunnelling, then CPU power becomes important because it requires a fair amount of horsepower to handle then encryption. That said, we generally use the LinkSys BEFVP41 VPN boxes at customer DSL and Cable sites because they're simple, cheap, and easy to configure for the average user.
