I have a 881 that we are configuring for proof of concept
purposes and have a question that I have been unable to
answer with online documentation and CSC.
Do I need both a Cellular interface and a Dialer interface? I have both configured the same at the moment and the router is making calls but have been told that it should work with just a Cellular interface.
The router will be making a VPN connection back to a concentrator for a site-to-site connection. Any thoughts on how to configure for a dynamic connection and not a static site-to-site VPN link?
