Mark,

What VPN should do (setup as) is a virtual gateway into your other LAN.
Office, Home, etc, etc.  It's a way to remotely attach to separate
LANs using the Internet.

So, in this case, both LANs know how to talk to each other via the VPN
just like a dial-up connection or a T1 per say.  Once the connections
are made as long as your firewall settings allow it you can have full
access to all ports UDP and TCP.  That is, you should setup our Linux
box to be the gateway, router, VPN, etc.

>From a Linux box the use of things like Samba, Fetchmail (and others),
and say Staroffice you can access Shares, Shared Printers, Windows
resources,
corporate mail (accept exchange mail but then again you could use
exchanges web interface and use Netscape of other Linux based browser
if you want) and corporate shares accessing MS Word, Excel stuff from
Linux.

The biggest thing for me is the office suite and star office is a good
choice
but you have to buy it now.  There is another free one but I can not
remember
the name of that one.

VNC and PCAnywhere will require the VPN to be active (or have the firewall
ports
open) to give you access to the remote PC.  It is simply a interactive
screen
sharing system.  But, it still requires access to that network resource
using
a VPN or open ports in the firewall.

As far as the VPN, I setup a VPN gateway as a firewall and VPN server for my
home
network.  All my access passes thru that box.  I have linux and windows
running
and have complete access to all my company resources.  We use FreeSwan, it's
a great free product out of Canada.  You IPTables (or IPChains for older
Linux
builds) for your firewall.  Between the two you should be able to get a VPN
into
your office and get access to all the network resources.

Hope this helps out.
Cheers-
Dan
