IPSec/PPTP through PAT on 2610

I have a 300 node network behind a 2610 running PAT. How can I enable potential VPN clients to connect from the inside network to the outside without assigning public IP's to each one?

This can be acheived only if the VPN terminating device on the outside is capable of NAT Transparent mode. The NAT transparent mode solves this problem by encapsulating ESP within UDP and sending it to a negotiated port (in most cases end-user configurable port assignment.
