Running backup a host

[ash786]

We currently log onto a real time price feed service via the web browser which goes out through the internet. In the even that our proxy goes down we loose access to the real time site. We have therefore invested in a back link which we use to acces this service.

We run internal DNS and are resolving the domain name to an external adddress via our back link, we have added the domain name to our DNS servers and and are successfully resolving the external IP address.

We would also like to take advantage of the existing connection via the internet in the event of the back link going down. However we would like the change over to be seamless and not have to carry out any manual intervention.

Is their a way of adding a backup host entry on our internal DNS to say in the event of the back link going down use the internet address.

I think more info would be helpful. You have a primary internet connnection and added a secondary (backup) connection (is this internet or direct to the service host?) How are you connecting (router/firewall/etc.) to both connections? When your primary connection fails you want all internet traffic to switch to the backup? Or you now use the backup connection for only the real-time feed and want to switch back to the internet connection when the back channel fails?

Couple ways we deal with both above for our clients:

Load balancing (via servers, firewalls, routers)
Address record cost (IPADDR1 - 10 - name, IPADDR2 - 20 - name)

Let me know if this helps
