Who is using 400 Mhz PC computers today ? You can find second hand computers, with miniature desktop cases, 1.6 Ghz Intel Pentium 4 processors, 256 or 512 Mo DRAM, for less than 100 euros.
They are not power hungry, and you can do a lot more than linksys soho routers and similar embeded products with them.
As soon as you are using OpenVPN on small embeded routers, the performance drop because the processor is not fast enough.
That’s why i think that for small enterprise routers, specially if you need VoIP and VPNs at the same time, it’s better to use standard PC hardware with a distribution like zeroshell.
If you try to use small soho embeded routers in the field with this setup, you will see that it does not work correctly as soon as the traffic rise to a few simultaneous calls with VPN traffic at the same time.
Zeroshell, Vyatta, and similar projects do not have this limitation.
More i’ve found the Zeroshell GUI very clear, fast and easy to use.
Behind the professionel usefullness of projects like zeroshell, there is a fantastic opportunity for informatic enthousiasts to learn more easily the IP network technologies.
