Currently our live web server uses multiple internal IPs that are NAT'd to an equal number of external IPs.
We are planning to take the web server down for maintenance over the new year holiday and need to redirect all these IP's to a single IP address on a temporary web server in order to show a maintenance message.
I cannot figure out hot to get this to work, trying to put multiple Static NAT statements for the same Internal IP reports overlapping errors and what I've read about Policy NAT seems to indicate it not suitable.
Any help would be appreciated, thanks in advance anf Merry Christmas for those who celebrate it.
So you want the www traffic of multiple external IPs forwarded to one single internal webserver IP correct? Please post your sanitized running config, the external IPs and internal IP you want to configure
