We have a small remote site with 30 users. It is connected to the internet via an ADSL ATM connection. We have installed a Cisco 2800 router between the ADSL and the ASA5510. We only have 1 IP address so the Routers external interface uses that. problem we are having is using the Site to site vpn as the local peer is behind the router using a private IP address. So the question is do we really need the router to terminate the ATM connection or can I remove the router and use the ASA 5510 directly connected to the ADSL router.
