Kind of. What we're trying to do here is provide a back-up only approach
for Internet service via NAT and VRRP/HSRP at the customer premise. The
problem is with people hosting applications on-site that require DNS
(www,MX,etc.). Trying to avoid using BGP as a back-up mechanism in this
case (for obvious reasons), if I could find a product that could act as a
authoritative DNS with a TTL of 0 or something, and only send replies for
applications when the primary IP was down or unreachable, and then
statically NAT our address over to the primary address at the customer
premise, I think we could have a pretty good solution for providing back-up
Internet service, including web, mail, etc. applications. I will
definitely take a look at all the listed products and would appreciate
anyone's input on this matter.
Thanks!
