I have an issue. My network consists of a Cisco 2821 Router, a ASA5510, and my LAN Switches (Cisco 2950s) I am getting rid of my T1, and got a new 3Mbps Circuit from another provider. Today was the activation date and I ran into a problem. The ISP bonded two T1s together on an adtran router and gave me an ethernet handoff to my cisco 2821 router. The problem is they assigned the WAN IP to the adtran, and then gave me just one public Routable IP Block. I connect from my Cisco Router, to the adtran fine, but now I need to configure another Interface on the Cisco Router, with a public address to go to my ASA5510's outside interface. Of course I can't configure another interface on the the Cisco Router in the same IP range, because it will overlap. All my site-to-site VPN's are on the ASA. Do I need to request a secondary range of IP Addresses so I can do this? Thanks.
