MetaFrame provides a way for users to access applications on a centralized
server.  It also dramatically reduces the overhead caused be data traversing
a slow link, by simulating a desktop or application in a remote location.
Have you ever used Terminal Services in Remote Administration mode on
Windows 2000 Server/Advanced Server or Windows Server 2003?  It's like
pcAnywhere, but quicker.  The ICA protocol is an optimized protocol to
provide a user with an interface back to am application over a slow link.
It's not to say that the ICA protocol isn't for a LAN environment.  In fact,
the more bandwidth, the better the session appears.

If you have any further specific questions, feel free to email me offline.

I have a couple of very basic questions about VPN management.  I just
recently started as a SysAdmin for a small non-profit that used to out
source most of its IT.  I worked in technical support on the client side of
a large university network, so I'm farely computer literate and capable but
a neubie to small office environments, system administration etc.

We currently have three employees accessing a centrally located database
over a VPN through a Watchguard Firebox system.  The performance is
horrendous due to the amount of data being sent back and forth.  It has been
suggested that we install a Citrix Metaframe system to drastically reduce
the amount of data being sent.  Two questions come to mind that I was hoping
someone could help me with:

Are three users on a VPN the bottleneck, such that a Citrix installation
will not drastically help.  
What is the bandwidth over a VPN, how is it shared and maximized?  
Am I correct in assuming that Citrix helps this only by reducing the amount
of data being sent over the VPN?

Thank you so much in advance!
