Thanks for the tip mdh. Yes the disk is encrypted, as is the VPN of course, but no SSL. There's also the VPN compression too. I will check the CPU usage, although I'd be quite alarmed if it was choking under the onslaught of a half meg ADSL line (2.8GHz Xeon, circa 2006)

Unfortunately this is a side project so will have to wait till the weekend to look again.

PS I didn't realise crypto cards were so cheap these days. I'm quite tempted, just for funnies!
