Hello all,

We're in the middle of changing our external ip for all our servers' and I have a question on what is the best way to implement it.  What we plan to do is change the nat ip address on the firewall and dns entry on the dns hosting server and then redirect all traffic of the old ip address to the new ip address so nothing will be lost.

Here's an example lets say 38.1.1.1 is the external ip of the server now and we want it to be 38.2.2.1 in the future.  what we plan to do is change the natting ip on the firewall then the public dns entry.  But since changes to public dns takes time to proporgate thru to clients, we are also going to do some type of redirection from 38.1.1.1 to 38.2.2.1 so no traffic is lost.  My question is what is the best and easiest way to perform this redirection?  should i do it internally using a proxy server (which we don't have and I have no experience setting up) or as our network engineer suggest that we use another asa behind firewall and setup routes on it to redirect traffic.

are there software that could perform this type of redireciton?  it sounds like an easy thing to do.  thanks in advance.
