Thanks, jamieburchell, for your quick reply.
My outlook files are indeed huge and I'm giving up on the idea of accessing them via the internet.
The real solution, as you point out, is to move my email and other outlook functions into the cloud, using something like google apps. Unfortunately (for me), I use outlook for mail, calendar, notes and tasks, and I sync the calendar, notes & tasks to my smartphone. I haven't found a way to duplicate this functionality in the cloud. Seems like google is missing a chance to really stick it to MS by not doing this; they're mostly there, but not quite...
Bottom line of this little discussion is that I can use a DNS 323 to access virtually all my files when I'm away, but I'm still looking for a way to handle outlook well. Next step: see if I can carry my outlook files around on a flashdrive, and plug into whichever of my pc's I'm using at the moment.
Thanks to both of you for helping me thing this through a bit more...

As outlook data files can be huge, I would also think that accessing them on your NAS over the Internet would be exteremly slow.
Not sure of your exact mail setup or what you are trying to store where but you might consider using Google apps which now has outlook mail and calendar support. You can access your mail from anywhere, and they look after the data. It will download 1Gb of mail to your outlook client as a local cache for speed. Our company moved over to it and got rid of our exchange server months ago. It's also fast.
