I would like to set up a Ubuntu linux box as a VPN Router and Firewall with logging where my local users are browsing.

I need to be able block selected local computers by IP or MAC address to internet access by IP address, domain, or key words.

I would also like to limit band width by user or service.

It would also be nice if could replace my Linksys VPN routers.

Local caching would be another bonus, since some PDF files we need access to are hogs.

While you can use ubuntu you do have full distros designed for this.

ipcop with addons will do everything you just said and you can do the admin work from a web browser.

endian is another option.

untangle is my personal favorite. It has modules that let you add the services you want to use. Most of them are free although they do have some ones you have to pay for like a kaspersky scanner.

Are there or any others you can recomend part of the packages.ubuntu? It makes it easy for ongoing updates.

The packages I was talking about are not part of ubuntu. Untangle has a built in update function that makes updates a breeze.

All 3 that I listed are full linux distros that you install and do a basic configure on. Past that it is done via a web interface.

If you really want to do it with ubuntu see the following links

These will get you started. You will then have to do a lot of extra work setting everything up. If you really want to learn Linux networking then go for it. If you want something that is semi easy to setup and just works look at untangle.

Would an Intel Atom processor with 2gig of ram be enough?

For the most part memory is the biggest issue and 2 gigs is enough. How many users are we talking about?

To give you an example I have 75 students on untangle on a 2.4 p4 with 2 gigs of ram. It is used as a web filter.
