RE: VPN overkill?

Hi here, I would like to add my views on this as I am responsible for over
45 VPN connections from our remote offices into a central office.  Before I
joined my boss had a very basic setup with ADSL (cheap) routers, client side
VPN DUN and a windows 2000 server as the concentrator.

We have slowly moving forward with cisco 837 routers, site to site VPN's
where the clients can be part of the interal IP schema.  In researching this
I proposed the following, a 505 Concentrator in the main office with a
separate 2MB line (due to the number of offices with have), with either a
small Pix or 837 in the remote locations.

Now I know that if you already have a Pix the 515e can support up to 100
connections but I am told if you terminate more than 50 then performance can
be an issue.

Hope this helps

Keith

All,
First off, good fun reading this list. Some really great advice and good 
thinkers on here. Thanks for the great questions and great answers.

So here's my issue. I have an IT infrastructure manager who has raised a 
requirement I find myself questioning.
We have a goal of connecting a remote office to a central office via a VPN. 
This manager insists that only acceptable way to accomplish this is by 
connecting 2 VPN concentrators. I debate this, noting that a PIX should be 
more than capable of handling this connection at the remote office and the 
only place the concentrator is needed is at the central office.
Am I completely off my rocker, thinking that a second concentrator for a 
single connection is a little overboard?

Thoughts?
Thanks,
Ted
