Suggestion for overlapping network

Hi

I have been asked to do a design for internet access infrastructure that will support the fact that all the clients are using unregistered public addresses.

I have started to put this together but need some help with the overlapping network. I figured on seperating the PIX and MS ISA PROXY server onto a seperate subnet then NAT all the clients onto 10.x.x.x (the new subnet) before they hit the proxy/PIX. The query I have is if we put a VPN concentrator off the PIX how will the VPN clients connect to the internal network using the unregistered addresses? Also what router should I use for the NAT as we have 5000 client PC's?

Take a look through this url on setting up NAT in overlapping networks.

Re: Suggestion for overlapping network

I have already seen the url but thanks anyway. The main problem is how do my VPN clients connect back through using the unregistered addresses.
