Re: VPN router recommendations for whole house VPN I personally use a Zyxel USG20 (and used a Zywall 2 in the past) for home VPN. For your speeds, you would need to step up to a USG200 or something like that (Anav would know best). I can VPN in using either SSL VPN or L2TP/IPSec.
One thing to consider with the old PC setup is how much power that machine will take. Old PCs tend to be piggish with electricity.
