Re: [beagleboard] BBB as a router w/ firewall capabilities
I'm not sure if you saw my original reply to this, which disappeared. In any case, I was able to max out my internet connection finally after applying the linux kernel update you suggested; before it maxed out at about 20Mbit/sec, and now I am reaching the 30Mbit/sec I pay for. However, I have a couple questions: 1. Where did you see the CPU usage of ksoftirqd? ksoftirqd does not show up in htop. 2. Have you since gained any insight into what changed between the kernel versions?

Re: [beagleboard] BBB as a router w/ firewall capabilities
There should be a cape to have these 2 NICS, thus using Xenomai -or Charles' Machinekit- is enough for such performances I think.
