I currently have a pix 515e setup as a firewall and vpn terminator. We will be moving our network to a new isp that will provide the firewall service, but i need to keep the pix for the vpn functionality. The pix currently has a public IP for the vpn but the new ISP want to do nat for the pix, so I have to give it a private ip. here is what the ISP sent me.

I'm new to VPN I would like some direction on where to find some documents on how to setup the cisco behind another router and without a public ip. Also can the pix have both interfaces on the same subnet?
Thank you
