I have several sites using Cisco 877 routers connecting to the Internet through a broadband connection. The ISP is giving us a dynamic ip to the routers. I want to reach an ACS server (using Dynamic DNS) to authenticate users to have access to the internet.
Can the router be configured to look for the Tacacs server using the server domain (www.whatever.com), instead of the ip address? If so, how?
You may consider using a dynamically negotiated IPsec tunnel and use the local ethernet on the router (mostly a private IP) to authenticate. You can force the interface to be used for authentication using the command:
ip radius source-interface ...
In that way, you will always have a unique ip for authentication.
