I am trying to configure a site to site VPN between 2 ASA 5505 firewalls. The one site has a static IP address, so I refer to that from the other sites IP, and create the tunnel group, but I am unsure on how to refer to the site that has different IP addresses every few months. I was thinking that it would be set with a dynamic peer, but was unable to configure that or know how to. I then used the defaultRAgroup with a pre shared key, but when i do a debug, the error message indicates an xauth failure, is it possible to turn that off?
I am open to ideas and suggestions, thanks for any help.
