NASLite Network Attached Storage

How do you all have your VPN's setup? Does everyone run two boxes, one to handle VPN login and then the NAS box or how is this being done?

I have my Linksys WRT54G router running alternative firmware (dd-wrt) that allows it to act as a VPN concentrator and once connected I simply connect to my NASLite box as if I was connected to the LAN at home. It works very well, apart from the fact that the router doesn't really have the power to cope with the encryption so the connection speeds aren't great. But for simply accessing a document from afar it works like a charm although it can't cope with streaming my mp3 files! I plan to replace the router with a Draytek Vigor router which has the 'grunt' to run the VPN tunnel as fast as my cable connection can upload data, i.e. around 380 kbs.
