I didn't realize you were actually looking for a reply until you sent the 
second message.

Since he never mentioned firewalls to begin with, just VPNs, I stuck with 
just the VPNs. 

But yes, it would be a good idea to implement some sort of client 
firewall. I think he needs to solve his VPN issues first, though!  It is a 
bit of a chicken-or-the-egg proposal, which to deploy first--but he seems 
focused on VPNs at the moment.

You could always allow for a Cisco router at the employees home; a DSL 
or
cable router in the 800 series of routers would work, with the option of 
a
hardware VPN accelerator.

Some models have a four-port switch installed, and you can configure the
router to allow only specific MAC addresses to connect via the VPN 
tunnel.
 So, Bob from Accounting can connect from his work issued laptop, 
without
any client installed on it (and as such, would never need updating) and 
he
can connect his printer to the switch, have a wireless home network 
access
point hooked up and the rest of his family--but only his laptop would
touch the tunnel (or if you prefer, his printer too).

The tunnel can connect to a PIX or a router at the business.

If VoIP was deployed, you cannot use QoS on the PIX, but you could on 
the
router.  So, if a scheduled backup job kicked off when the employee was
connected, VoIP would suffer if you terminated the tunnel on a PIX.  But
if its a router-to-router connection, you could configure for VoIP 
traffic
to receive priority.

Teleworking

I'm about to embark on a teleworking project and would like to ask you
guys the following...

I was going to be using Cisco-based 3des VPNs out to clients who will 
use
the vpn client s/w loaded on their machines, an adsl connection and 
citrix
for a remote desktop.

I was going to employ a securID or similar box to provide additional
security.

Could anyone out there recommend any other options?  I want the 
connection
to be very secure and allow for a concurrent usage of up to 50 clients
coming in at any one time.

Your help will be much appreciated...

Regards,

Dave.
