[Soekris] OpenBSD home firewall

[Jesper Andersen]

Currently I have an old AMD K6 233MHz, 128 MB ram PC running linux as 
firewall, openVPN box in my parents house. I was thinking about replacing 
it with a soekris board with OpenBSD. To have a smaller box using less 
power and to try out OpenBSD in real use.

I was thinking about the 4501-30 or 4801-50. The question is how much is 
needed. Currently I see 10-15% cpu usage from openvpn when transferring 
1mbit/sek. I expect openvpn don't have to handle more than 2mbit/sek 
traffik. I saw someone say something about interupts from the NIC setting 
some limit to how much traffic this boards can handle. Is there any truth 
that. What is the limit? I expect it will have to handle 20mbit speed 
within the foreseeable future.
Can I expect the 4501-30 to be enough or should I spend a bit more for the 
4801-50, also to have a bit more spare resources for later.
