VPN to be installed onto a LAN that has ADSL internet connection

Hello. I need to reconfigure our network to also fit a VPN (via a Cisco 1711 w/hardware module). Presently the ADSL line comes into a Linksys router, and the LAN is directly connected to it.
I would like to know what Cisco router would be suggested to replace the Linksys? As well as if a PIX would be included (security is becoming a high priority). Could you also include the physical layout order of things, and the interfaces with public or private addresses?
Thanks in advance.

If you wanted to use the 1711 in this scenario you would have to keep the Linksys in place, and then place the 1711 between it and your LAN, so LinkSys->1711->LAN. This is because the 1711 has an Ethernet WAN connection not ADSL.

As the 1711 has integrated router, firewall, virtual private network [VPN], QoS, and WAN interfaces your need for a PIX is reduced, unless you would feel more secure having one. Then you would have Linksys->1711->PIX->LAN.

Thanks Kemp.
If I was to use the model that you finalized your comment with, would the 1711 be providing NAT? Would the Linksys, 1711, and PIX all have public addresses? And also, we have a Cisco 1700 series (1720) router with a WIC DSU/CSU 56/64k. Could that be used to replace the Linksys?
Thanks.

In this case the 1711 would be providing you NAT and you security. YOu can add custom Access-lists, to add more security.

Here is some info on the 1711 including some scenarios:
