I am trying to read the configuration of haresources of heartbeat to see how can I make this possible. I have an IP given by my ISP and my servers are running heartbeat. So I want to turn on a network card once it becomes primary server. This ip is something like 74.1.1.2 with a gw like 74.1.1.1, I cant have a other ips like 74.1.1.3 and 74.1.1.4, it might conflict with the isp.
I think I can maybe have something like 192.168.201.1 set on this card and add virtual interface with 74.1.1.2. It doesnt seem ideal. Can I add a default gw on haresources too?
What would be the best approach to this.
