Re: Any Cisco ASA Guru here

Does the ASA use the DNS server to verify if the connection is up? Sounds like that's what is happening.

I'm no expert, but on all of our system we use 8.8.8.8 as primary DNS, and 4.2.2.4 as secondary. We do not have any kind of failover setup.

Failover is accomplished on an ASA through the use of SLA responders, not DNS. However, 4.2.2.2, 8.8.8.8 and the like as targets for these responders.
