Hi

Iam looking for the best way to ensure my server ( application ) remains available for all my users (on web/LAN/WAN ), when my primary ISP link fails.

My server is behind a firewall on which both my primary & secondary links land.

I have already assigned multiple IPs (both ISP's static IP) to the 'A' record ( host.example.com ) in the DNS. However in a round robin scenario is there a way I can ensure that my web user will not see a "cannot dislay web page" error ever ??
What are the better methods to achieve this??
