My main Domino server in my office has a public IP so that I can retrieve information from my Lotus Notes Database from my home. I have a second (failover) Domino server within my office network which does not have a public IP. How do I set it up so that if my main Domino server crashes, the second Domino failover server located within my office can assume the public IP of the main Domino server so that I can retrieve my Lotus Notes data?
Is there any other way to set it up to achieve the same goal?
You’ll need to configure this in network address translation outside Domino.
Typically, the hardware or software that would do this would be a load-balancer, and would cost a lot of money.
If you really wanted to do this cheaply, I’d expect the best way would be a Linux-based software firewall. You could (for example) set up a daemon to check for the availability of each machine and rewrite the firewall’s address translation table if your primary server is down. You’d probably still need to tell the firewall to reload it’s configuration.
Thanks for your reply. I understand where you are coming from. But my internet provider refuses to give me a second public IP!! Of course if I pay him a lot of money, he is willing to do it!!!
What if I cluster the two domino servers also as a windows 2003 server cluster? Can I not assign two real local IPs to the servers with one floating (virtual) IP that translates into a public IP?
