The main issue isn't the speed of the > crypto part but the bus+dma glue. And also stability. I've experience system crashing with the soekris vpn1401. It was kinda strange. Existing things worked (like an opened ssh connect, the box is a gateway), but I couldn't even fork() new processes, use apache, open new ssh connections to the box, anything. And the interrupt load was also a bit too high. Anyways, it's a different issue. Silicom has drivers for both windows and linux, and they support AES. I wasn't able to download the driver (got an empty page), so I don't know whether its opensource or not.
