Hi, I have a Cisco Pix 515 and a Concentrator for the VPN side. I'm getting rid of these 2 and replacing them with 2 ASA 5520 (active/standby). I hope to eventually move the site to site VPN's and client VPN's over at some point and hope it's like the Concentrator to set them up. I was just wondering what the 5520 VPN IP will be? I guess the ASA 5520's "outside" interface will have the same external IP as the Pix (after migration), but will the VPN's also use this address or can I use the public IP the concentrator after migration or will it simply use the "outside" IP of the ASA?
