Configure Private/Public Network

[BrianSc]

Our small group uses a Cisco 1605R configured now with only our public IP range (216.54.xx.xx). I want to take all client workstations off the public range and asign private addresses (10.26.XX.XX). How can I configure the router to allow these clients to have access to the internet and communicate with the public range as well? The router configuration is :

!
service timestamps debug uptime
service timestamps log uptime
service password-encryption
no service tcp-small-servers
no service udp-small-servers
!
hostname XXXXXXXX
!
enable secret 5 $1$Snwh$9YWEOHTT9mbLnKbfAu7lu/
