X25 Failover seems to be a Cisco Interface failover feature. But does it provide NAT IP address failover??? What is the IP address failover feature?? Eg. X25 Failover can failover from Ethernet 0 to Ethernet 1. But what I need is IP NAT failover. Eg. Currently I have a public static ip of 203.155.155.155 NAT to 192.168.100.5 computer on the internal network. If the 192.168.100.5 computer shutdown. I need IP NAT failover to redirect 203.155.155.155 NAT to 192.168.100.7 computer immediately. What's this feature and how to program it???? Thanks
